36 REPORT OF THE VERMONT STATE GEOLOGIST Brick Clays REPORT As pointed out by the writer,' there are in the State tremendous amounts of glacially-transported clays, classifiable as Estuarine OF THE Clays, Lake and Pond Clays, Flood-plain and Terrace Clays, Drift or Boulder Clays, and Seasonal or Varve Clays. Their abundance and wide distribution are indicated by the number of brick dwell- ings in the country, oftentimes in out-of-the-way places, as well as STATE GEOLOGIST in urban centers. The largest known deposits are found along the Connecticut ON THE River and other streams, but deposits also occur along the lake shores and in former natural depressions which were filled with the clay sediments by streams flowing from the retreating ice sheet. MINERAL INDUSTRIES AND GEOLOGY ljrick Yards OF Considerable brick yards have been in operation in the past at East Ryegate, Westminster, Putney, and Bennington but, as far as the writer is informed, none of these plants is at present in VERMONT operation. 1935-1936 THE DRURY BRICK AND TILE COMPANY, INCORPORATED Office, Essex Junction. Officers: President, H. D. Drury; vice-president, H. K. Drury; treas- urer, M. W. Drury. Quarries and kilns at Essex Junction. Products: Sand-struck and water-struck bricks. I Capacity, six million sand-struck and one and one-half million water- struck bricks annually. An analysis of the clay, made some years ago by the writer, TWENTIETH OF THIS SERIES gave the following results: SiO2...............................................53.69 A1203..............................................21.24 Fe203..............................................8.65 I Ti02................................................41 MnO................................................02 CaO................................................2.84 MgO...............................................1.03 Na2O..............................................1.78 K20................................................3.94 H20...............................................5.36 ELBRIDGE C.

REPORT OF THE STATE GEOLOGIST ON THE MINERAL INDUSTRIES AND GEOLOGY OF VERMONT 193 5-1936 I TWENTIETH OF THIS SERIES I ELBRIDGE C. JACOBS F.G.S.A. State Geologist RELIEF MAP OF VERMONT Vermont Mineral Industries The mineral industries of the State, as a whole, are rapidly recovering from the depression. Comparing production in 1935 (the latest available figures for a calendar year) with those of 1933, one finds that the asbestos tonnage has increased 83.8 per- cent. lime 45 percent, talc 17.7 percent, granite (cubic feet) 16 percent, and fire clay 10.5 percent. Comparative figures for marble and slate are not available. In the lime industry prices per ton are about the same as in 1933, talc prices have improved 10.6 percent, while granite prices per cubic foot have increased 42.3 percent. In the last Report references to the geology of the various mineral deposits were given. It is not thought necessary to repeat them here. Marble Production Vermont continues to he the greatest producer of marble in the United States (and probably in the world), exceeding her nearest competitor, Georgia, by about 46 percent in "footage." The latest available figures from the Minerals Yearbook, United States Bureau of Mines, for 1934 are as follows: Building and monunsental (rough and finished) Other uses Total Slate Cubic feet Value Short tons Value Short tons Value Alabama ......... 26,480 $ 95,441 46,070 $ 45,451 48,320 $ 140,892 Arkansas ..................................... 1 510 7,356 California ............... 1 1 1 990 12,134 Georgia .......... 236,720 969,140 19,660 20,114 39,740 989,254 Massachusetts 5,470 17,566 360 576 830 18,142 Missouri ......... 70,220 169,519 120 900 5,930 170,419 New York 8,690 26,420 9,410 47,032 10,140 73,452 Tennessee ........ 141,990 518,659 3.090 12,416 15,070 531.075 Vermont 432,170 1,190,249 13,330 17,063 50,060 1,207.312 Other States 2 43,180 207,888 3,520 32,483 5,690 220,881 964,920 $3,194,882 95,560 $176,035 177,280 $3,370,917 1 Included under "Other States."
