OUTDOOR MONUMENT CONSERVATION ASSESSMENT

WORCESTER, MASSACHUSETTS

1898

Date of recent site visit: 10/20/16

Artist: O’Connor, Andrew, Jr. (1874-1941) Foundry: T.F. McGann & Sons Company Title: 1898 Date: Dedicated April 19, 1917, in Armory Square (name changed to Wheaton Square), with 50,000 people in attendance. Location: Wheaton Square, Worcester (corner of Grove and Salisbury Streets). Wheaton Square is named after Homer J. Wheaton, the first soldier from Worcester who died in World War I, on February 28, 1918). Dimensions: Sculpture: Approximately 8’. Base: H 4’1” x W 3’ 9 ½” Inscriptions: Signed “O’Connor” on proper left side of sculpture, signed: T.F. McGann & Sons Co/, MA FDY”. On front of base (lithochromed carved stone letters): To The Men of Worcester/ In the War With Spain/1898 Description: A standing figure of a Soldier from the Spanish-American War, dressed in a loose shirt, torn at the shoulder, sleeves pushed up. His proper right hand rests on his proper right hip. A rifle is slung over his proper left shoulder and he holds a hat in his proper left hand. Around his waist is a cartridge belt inscribed: MASS. The sculpture is attached to a low square granite base. Historic Notes Brief Artist Biography: Andrew O’Connor, Jr. was born in Worcester, the son of Andrew O’Connor (the artist who sculpted the Fisher Boy of the Chamberlain Fountain). He studied under his father and worked for the sculptor William Ordway Partridge for the World’s Fair in in 1891-2. He met John Singer Sargent and assisted him with the plaster reliefs in the rotunda of the Museum of

Wheaton Square Page 1 1898 by Andrew O’Connor, Jr. 2

Fine Arts. He was also commissioned by Daniel Chester French to make the monumental bronze doors in Saint Bartholomew’s Church in New York. O’Connor, Jr. lived and worked in Paris from 1903-1914, where he was influenced by Jules Dalou and Auguste Rodin, and then worked from 1914 to the mid-1920’s in Paxton, MA. Later in life, he moved back to Europe, first in Paris and then in Ireland and London. Additional notes: The sculpture was a gift of Camp 28, U.S. War Veterans, at a cost of $7,000.00. One of the artist’s students, Vincent S. Wickham, was a model for the sculpture. Smithsonian Inventory of American Sculpture # 87630013. SIRIS lists 49 works of art in American collections by Andrew S. O’Connor, Jr.

Additional note # 2: a lantern slide photograph of the sculpture is available in the Smithsonian Online Collection Search Center, image number SSC S001825, Archives and Special Collections, Smithsonian American Art Museum. It is not clear from the label and image if this is the monument in Worcester or a smaller bronze version, but it does show the bronze before any corrosion occurred.

CONDITION

Above: Overall of Wheaton Square, with Andrew O’Connor Jr.’s bronze sculpture. The square is to the side of a Salisbury Street.

Wheaton Square Page 2 1898 by Andrew O’Connor, Jr. 3

STRUCTURE

The sculpture of the Spanish-American War soldier is in fair structural condition, with heavy copper alloy corrosion from acid deposition and a large hole in the soldier’s hat on the reverse from a casting flaw. Conservation treatment required includes repairing holes in the cast, reducing loose corrosion, repatinating, and applying a protective coating to prevent further damage.

Above: image showing Wheaton Square landscaping. The bushes appear to have been planted to prevent access to the sculpture, but they also block viewing the granite base. Litter/garbage found in the park included empty “nip” liquor bottles, Mardi-gras beads, and a whole dead fish.

Wheaton Square Page 3 1898 by Andrew O’Connor, Jr. 4

Above left: Overall of bronze sculpture. The sculpture was originally a medium-dark brown, but the green copper sulfate corrosion and black copper sulfide corrosion has obscured the visual reading of the sculpture. Right: view from front/proper left. The dense bushes prevent people from reaching the granite base, but they also prevent viewing the inscription on the stone. A new planting plan could add visual interest to the area but also allow viewing the entire memorial.

Left: Head of soldier from below, showing casting lines at jaw. Although cast by T.F. McGann & Sons, a well-known bronze foundry in Boston, the bronze has some casting flaws and areas where the bronze was not completely finished and smoothed before patinating. It Is not known if this was intentional by the artist, but comparison to other works by the sculptor would indicate if this type of finish is typical of O’Connor’s work.

Wheaton Square Page 4 1898 by Andrew O’Connor, Jr. 5

SURFACE

Above left: sculpture showing heavy corrosion. Right: Areas of surface damage caused by paintball vandalism. Paintballs are made of polyethylene glycol and dye, and can permanently stain the corroded bronze. Cleaning, removal of loose corrosion, and repatination will almost completely mitigate the stain. Areas of black corrosion are slight raised “islands” of corrosion caused by copper sulfide corrosion.

Above: heavy corrosion has removed surface detail in rifle, proper right hand and on belt buckle. Repatination will restore the sculptural form.

Wheaton Square Page 5 1898 by Andrew O’Connor, Jr. 6

Above, left and right: a hole in the soldier’s hat, proper left side rear, appears to have been caused by an iron pole section placed during the casting. It is unusual that this was not drilled out after casting and filled with bronze. The open hole allows water to enter and requires rust corrosion reduction and filling.

Above: The lithochrome paint in the cut granite letters has deteriorated. Forty one letters will require repainting.

Wheaton Square Page 6 1898 by Andrew O’Connor, Jr. 7

DISCUSSION and RECOMMENDATIONS Wheaton Square is in a high traffic area. The Spanish-American War Memorial 1898 by Andrew O’Connor, Jr. is not well-viewed due to a dense planting of bushes with some overgrowth. The current landscaping obscures the granite base. A new landscape plan, in addition to conservation treatment, would better present the outdoor sculpture. The sculpture had deteriorated from exposure pollution and acid rain, and some surface detail is gone due to heavy copper alloy corrosion. There is a large hole in the soldier’s hat that should be filled, and the entire sculpture requires cleaning, repatination to the original color, and a new protective coating. After treatment, the sculpture will require annual maintenance care.

SCOPE OF WORK: 1. Wash all surfaces of bronze with mild detergent such as Orvus™ (sodium lauryl sulfate) and water, followed by repeated water rinse. Remove bird guano or other accretions. Assess attachment method. 2. Mechanically remove loose corrosion products over bronze surfaces with Orvus detergent and water using nylon pads, bronze wool, or small brushes. 3. Power wash bronze (low pressure, 800 psi, fan-shaped nozzle, 12-14 inches from surface) as needed to complete removal of loose corrosion and dirt to achieve clean surface. 4. Clean granite base with Vulpex detergent and power wash at low pressure. 5. Protect all stone surfaces with heavy weight plastic sheeting. 6. Repatinate all bronze surfaces with aqueous chemical reagents and heat torches to appropriate historic color (ferric nitrate and potassium permanganate are recommended) to a medium dark brown tone. Examples of colors will be provided beforehand for review. 7. Fill losses at braze lines to prevent water infiltration. 8. Clean out loose iron corrosion at hat, and fill hole with bronze rod planished to surface or fill with PC-7 epoxy toned with dry pigments to match bronze. 9. Apply protective coat of Incralac (Acryloid B-44) in toluene to all bronze surfaces. Specifically, apply one-two brush coats and one-two spray coats to achieve an overall even layer approximately 1 mm thick. 10. Wax bronze with a hard paste wax and buff with soft lint-free cloths or nylon fabric. Train a city employee or representative on site to carry out maintenance. 11.Replace all lithochrome in cut stone letters on base. 12. Supply a written report on the treatment to the City of Worcester with photographic documentation including digital images before, during, and after treatment images. Report will include all materials and methods used in treatment.

WORCESTER, MASSACHUSETTS

The Celtic Cross

Date of site visit: 10/20/16

Artist: Calgagni, Joseph (sculptor) Title: Celtic Cross Date: 1977 Fabricator: Barre Guild, VT Material: Granite Location: North side of Worcester City Hall Dimensions: 15’ tall, plinth 46 ½ x 54” Smithsonian Inventory of American Sculpture #: 87630010

Description: The Celtic Cross is a tall highly decorated memorial, a gift from the Irish community that commemorates the 150th anniversary of the first Irish settlement of Worcester, in 1826. Bas-relief panels depicting scenes from Ireland and Irish symbols are carved into the cross. The 15' high Celtic Cross stands on a 54" by 46" base. It was created by Joseph Calgagni and fabricated at the Barre Guild and dedicated on September 18, 1977.

In the center of the upper part of the cross are shamrocks, surrounded by four crests representing the four provinces of Ireland: Leinster, Ulster, Munster and Connaught. On the vertical front are: the Round Tower of Ardmore in County Waterford and a wolfhound; St. Bridget's Cross and shamrocks; a sailing ship; a Claddagh Ring; a scene of men digging Blackstone canal; an endless knot; a Celtic cross over American and Irish flags; an eagle standing on arrows and an olive branch. On the side to the left of the front are the names of the counties along a ribbon and a map of Ireland.

On the upper back of the cross, the upper part is the same as the front. The vertical part has panels depicting: thatched roof cottages, three small shields, Christ's Church on Temple Street, a motif of tools and a section of railroad track. On the side to the right of the front are county names and an 1829 map of Worcester noting the Canal Basio, Scalpintown, the Meadows, Dungarvan Hill, and Christ's Church.

Celtic Cross Page 1 Celtic Cross 2

The front of the base is inscribed:

COMMEMORATING THE 150TH ANNIVERSARY OF THE FIRST PERMANENT SETTLEMENT OF THE IRISH COMMUNITY IN WORCESTER 1826 - 1976

The same inscription in Gaelic

On back of cross:

WORCESTER BECAME A CITY THROUGH THE EFFORTS OF PEOPLE FROM ALL PARTS OF THE WORLD. EMIGRANTS FROM IRELAND HELPED BEGIN THIS DEVELOPMENT. THEY FIRST ARRIVED IN 1718 AND ASSURED THE TOWN'S SURVIVAL AS A SETTLEMENT. IN 1826 THE COMING OF IRISH CANAL-BUILDERS BEGAN WORCESTER'S FIRST ETHNIC COMMUNITY. THIS MEMORIAL IS DEDICATED TO THESE PIONEER IRISH AND ALL WORCESTER RESIDENTS OF IRISH DESCENT.

(On back of base:)

WORCESTER IRISH MEMORIAL COMMITTEE

Historic Notes There was some disgreement over the placement of the Celtic Cross on the Worcester Common, next to City Hall (the controversy was about the site selection, not the design), but the monument was installed in 1977 and has not been moved.

Celtic Cross Page 2 Celtic Cross 3

Detailed dimensions:

Celtic Cross Page 3 Celtic Cross 4

CONDITION STRUCTURE The Celtic Cross is in very good structural condiiton. No movement, fissures, or cracks were noted at the assessment. The Cross is squarely set on its base.

SURFACE Because the granite cross is on the north side of City Hall, facing north, it gets little daylight, particularly on the back side, where a lack of sun, a dry environment, and a damp microclimate has caused moss and lichen growth. This biogrowth, if left unattanded, can multiply and cause damage to the stone by releasing oxalic acid. The treatment is simple, but must be carried out every two years. The stone should be treated with an enzyme digester (a natural product that causes no harm to city drainage systems), followed by washing with Vulpex, a stone detergent, and copious rinsing.

Above: Celtic Cross, overall from front. Note bio-growth on pavers behind monument.

Celtic Cross Page 4 Celtic Cross 5

Left: detail of back side of base with extensisve biogrowth. This side of the monument gets little sunlight and is close to City Hall building. Air flow is very low. Right: detail of biogrowth and lichen. Lichen and moss produce oxalic acid, which can damage the granite.

Left: back of monument, above plinth. Although off the ground, bio-growth is evident. Right: proper right side of base showing bio-growth. Washing every other year will prevent growth of moss and lichen.

Celtic Cross Page 5 Celtic Cross 6

Clockwise from top left: image looking up, from reverse, detail from front, image of ship panel, detail of Ireland map showing strat of lichen and bio-growth.

DISCUSSION and RECOMMENDATIONS Located on the north side of City Hall, the Celtic Cross receives very little sunlight and there is a damp microclimate on the reverse side, encouraging bio-growth. Continued biogrowth will damage the granite. The monument should be cleaned every two years with an enzymatic solution and a stone detergent. The surrounding pavers should also be cleaned to reduce the presence of bio, matter.

SCOPE OF WORK

1. Pre-treat all areas of biogrowth with Nilodor Professional’s Edge Bio-Enzymatic Urine Digester (place two tablespoons of digester in a bucket of water and apply by brushes or sponges). The enzymatic digester is available through janitor suppliers or online. 2. After 10 minutes, wash oll surfaces of the granite with Vulpex stone detergent (potassium methyl cyclohexyl oleate) in water followed by copious water rinsing, using brushes to agitae the dtergent to gently remove biogrowth. Vulpex is available from Talas Online and other suppliers.

Celtic Cross Page 6 Celtic Cross 7

3. The surrounding pavers may also be washed with Vulpex and power washed at low pressure (800 psi, fan-shaped nozzle, 12-14 inches from surface) as needed to complete removal of loose corrosion and dirt to achieve a clean surface. 4. Supply a written report on the treatment to the the City of Worcester with photographic digital documentation in high resolution JPEF or TIFF format.

Fisher Boy

Date of site visit: 10/13/16

Artist: O’Connor, Andrew (1846-1924), Worcester, MA Title: Chamberlain Fountain (Fisher Boy) Date: Cast ca. 1914, dedicated August 14, 1915. Relocated 1955, reinstalled 1956. Base Fabricator: Kittredge, John J., Worcester, MA Dimensions: Sculpture 60 1/2", Basin: L 12’ ¾”, H 41” Location: Originally installed in Washington Square, the monument was moved to Elm Park in 1956.

Description: The fountain sculpture depicts a young boy dressed in a bathing suit standing on a small square granite plinth in the center of a rectangular fountain basin. The sculpture originally had a fishing pole, but that has been missing for some time. The fountain basin was designed as a watering trough for horses.

Historic Condition Notes on Vandalism and Repair: It is not known when the fishing pole went missing, but it was not pictured in a Worcester Telegram article from 1957. In 1966, vandals cut through one of the ankles, and in 1978 the other ankle was cut and the sculpture was knocked over. The ankles were reportedly repaired by the Vocational School.

Specific Dimensions and Notes:

Fountain dimensions and locations of basins.

CONDITION SUMMARY Both granite base and sculpture are in poor condition. The sculpture was vandalized and cut off at the ankles. Despite an attempt at full restoration, the ankles were not fully repaired, although the join alignment is good. The patina is gone, the original fishing pole is missing, and there is graffiti in both red and white paint on the figure. The granite fountain base has been severely sand blasted, removing surface detail and resulting in damaged and deteriorated stone.

Front of Chamberlain Fountain/Fisher Boy Monument in Elm Park, facing pond. Although the figure is securely attached to the base, there are some gaps at the proper left corner of the self- base. These were previously filled with caulk, which is now deteriorating. The caulk should be removed and replaced with lead sheet.

The reverse of the Chamberlain Fountain, facing Pond. The entire park is 60 acres, and provides many walking paths for residents. The pole in the front of the sculpture appears to be a light/electricity source, and just to the right is the didactic sign for the fountain. The sign is very deteriorated and requires replacement.

Left: detail of artist signature in proper left side of bronze self-base; heavy etched corrosion in the bronze from exposure to acid deposition, and remains of modern caulk used to fill gap. The sculpture may be able to be reset, and the correct historical fill would be a thin lead sheet. Right: detail showing previous repair to ankles, which were cut by vandals and the sculpture toppled. Although the alignment was good, there are still gaps in the join line and the appearance is poor. The original appearance would likely have been a medium to medium-dark toned brown.

Left: red paint graffiti on bronze leg and top of self-base. Note small pin for attaching fishing pole. Right: red paint is removable with acetone: ethanol mixed 50:50, indicating the red paint is likely an acrylic resin.

Left: top surface of fountain, showing historic basins for horses and drain holes. The entire surface of the granite was overly blast cleaned, removing surface detail, causing some granite loss to corners, lamellar deterioration, and “sugaring”. Sugaring is a description of loss of the granite around grains of stone, presenting as a deteriorated, sometimes “sparkling” surface. The over cleaning was likely caused by aggressive sand blasting.

Fisher Boy Page 6 Fisher Boy 7

Left: image from an undated newspaper article from the Worcester Historical Museum, likely from the late 1950’s. The ankles have been repaired, but the overall surface is bright green from acid deposition corrosion, and the fishing pole has already gone missing. Some residents have called the Fisher Boy, the “Boxer” or the “Pugilist”, because his stance without his fishing pole. Right: the only image found of the original fishing pole, from the Worcester Magazine of September 1915. The fishing pole appears to have been fashioned after a bamboo rod, attaches to the bronze self-base at the left, but notably rests on the Fisher Boy’s proper left arm, instead of his hands. His hands may have held a hook or bait material, and will be examined more closely. A new fishing pole can be fabricated in bronze (and/or copies made in fiberglass).

GRANITE BASE

Left: the surface of the granite had been badly damaged by sandblasting, with either too large a grit or more likely too much pressure, and with the blast nozzle held too close to the surface. Damage includes some deterioration of the original striations at the stonemason’s inscription, John Kittredge. Right: chip loss to an outer corner. There is also some damage at the bottom of the base from lawn equipment.

DISCUSSION and RECOMMENDATIONS

The Fisher Boy monument is in poor condition and does not represent the sculptor’s original intent, and is further deteriorating in its current state. It is also a beautiful sculpture, and well sited in Elm Park.

Fisher Boy Page 9 Fisher Boy 10

The granite base has been badly damaged by over aggressive sand blast cleaning. Treatment should include only gentle washing, and the consideration of local consolidation at area of stone delamination with ethyl silicate.

The bronze requires a full conservation treatment, and the sculpture should be removed and brought to a conservation studio for work. The fishing pole should also be replaced. The new version could be bronze or fiberglass, and some extra copies should be made. A recommended sculptor and fabricator for the fishing pole is Robert Shure of Skylight Studios in Woburn, MA, who can model and sculpt the pole, and provide versions in bronze and fiberglass.

Didactic park sign to the left of the Chamberlain Fountain is outdated and deteriorated, and should be replaced. Enameled metal would be a good replacement. A possible vendor would be Winsor Fireform in Turnwater, WA.

SCOPE OF WORK

REMOVAL, TRANSPORT TO CONSERVATION STUDIO, AND RE-INSTALLATION The bronze figure will require removal, wrapping, and transport. Recommended vendor for this work are USArt in Randolph, MA (contact George Hagerty), Artex in Somerville, MA (contact Christa Balderacchi), or Fine Arts Enterprises (FAE) in Boston. Due to the fragility of the base and the sculpture, a professional art installer is recommended.

Fisher Boy Page 10 Fisher Boy 11

TREATMENT SCOPE REPLACEMENT FISHING POLE The image of the Chamberlain Fountain’s original fishing pole can be used for re-fabrication, possible using a stick of natural bamboo as a model. Choices for materials include casting in in bronze, or making it in fiberglass and making multiple casts in case of theft. Skylight Studios in Woburn, MA can fabricate a model and have casts made, using the original bronze attachment pin on the bronze self-base. Estimated cost varies based on materials, but would likely be $1,800-2,500.00 in fiberglass, more if made in bronze.

BRONZE SCOPE 1. Wash all surfaces of bronze with mild detergent such as Orvus™ (sodium lauryl sulfate) and water, followed by repeated water rinse. Remove red paint graffiti. Assess attachment method. 2. Mechanically remove loose corrosion products over bronze surfaces with Orvus detergent and water using nylon pads, bronze wool, or small brushes. 3. Power wash bronze (low pressure, 800 psi, fan-shaped nozzle, 12-14 inches from surface) as needed to complete removal of loose corrosion and dirt to achieve clean surface. 4. Repatinate all bronze surfaces with aqueous chemical reagents and heat torches to appropriate historic color (ferric nitrate and potassium permanganate are recommended) to a medium dark brown tone. Examples of colors will be provided beforehand for review. 5. Fill small losses at ankles with PC-7 epoxy, toned with dry pigments to match patinated bronze. 6. Attach newly made bronze fishing pole to base, and braze to inner arm. If the fishing pole is made of fiberglass, adhere later with PC-7 epoxy. 7. Apply protective coat of Incralac (Acryloid B-44) in toluene to all bronze surfaces. Specifically, apply one-two brush coats and one-two spray coats to achieve an overall even layer approximately 1 mm thick. 8. Wax bronze with a hard paste wax and buff with soft lint-free cloths or nylon fabric. 10. Supply a written report on the treatment to the City of Worcester with photographic documentation including high-resolution digital images showing before, during, and after treatment images. Report will include all materials and methods used in treatment. 11. Provide written annual maintenance directions, with specific directions for graffiti removal. 12. Coordinate with fishing pole fabricator to attach replacement. 13. Coordinate with bronze sculpture installer to confirm method to attachment to granite base. Fill gap between bronze self-base and granite base with lead as necessary, using a soft wood tool and small hammer.

Fisher Boy Page 11 Fisher Boy 12

STONE SCOPE 1. Washing all surfaces with Vulpex detergent, using soft brushes. Rinse. 2. After cleaning, consider the use of isolated applications of ethyl silicate (Conservare OH100) to reinforce stone. 3. Remove loose mortar and replace with historically correct lime mortar (Cathedral’s Jahn Mortars recommended). 4. Remove plastic drain covers and reattach with caulk matching stone for visual improvement.

Worcester Monuments Condition Assessment Worcester DPW & Parks

Edward Winslow Lincoln Memorial Gate

The Lincoln gate is a freestanding fieldstone wall situated at the Russell Street entrance to Elm Park, commemorating the first commissioner of Worcester’s parks. It is constructed of rounded cobblestones and consists of two large piers which frame the entrance to the park, connected to two low walls with integral sitting benches and terminating with two short piers. The gate itself if figurative; there is no actual gate to be closed, and the construction is open on either end of the low piers.

The physical condition of the masonry work is relatively sound but in need of attention before damage becomes significant. Roughly 70% - 90% of the mortar joints are cracked, and show evidence of prior repair with differing materials, particularly on the horizontal surfaces on the tops of the piers. The repair mortar as well has cracked in many locations. The watertightness of the top of the wall is of paramount importance as snow an ice which melt and run into the interior of the pier through cracks, can refreeze and heave the or split the pier.

The stone slabs for the benches show some minor spalling consistent with their age and type. Sealers could be used to slow or prevent this, but would not be authentic on this historically significant monument, therefore, they are not recommended.

In total, 4 stones are missing. A few stones are cracked.

Very minor grafitti was observed, and there is some discoloration on some areas of the structure.

There are 2 bronze plaques laid up into the masonry, which are showing a greenish patina and are missing some bolts.

The following scope of work is required for the restoration of the gate:

1. Clean all masonry work following Preservation Briefs 1 and 38 by the National Park Service, generally using a medium pressure wash of water or mild approved detergents to remove dirt, plant growth and minor grafitti. Protect plaques from washing operations. Do not pressure wash benches.

2. Source local stones with a size and appearance consistent with those in place on the structure, to replace the 4 stones that are missing.

3. Sample and test the existing mortar by a qualified lab specializing in historical mortars, such as American Heritage Group, to determine the proper mortar mix for repairs. Remove all loose mortar and all repair mortar which is not period correct, taking care not

Winslow (Lincoln) Gate Page 1 to damage the stones, and repoint the entire wall following Preservation Brief 2 by the National Park Service. Where stones are cracked, repair by epoxy injection.

4. Clean and repatinate bronze plaques using procedures explained for similar plaques within this project manual, and replace hardware where missing.
