To THE PRES IDENT AND F ELLOW S O F HARV ARD COLLE G E : HE of M u seu m of o T staff the consists a Direct r , eight Curators, A o A o o . two ssociate Curat rs , and a Preparat r The two ss ciate o a o o o Curat rs and three of the Cur t rs serve with ut remunerati n , n h r o offi of o and a Ot e Curat r is an cer instructi n in the University , giving somewhat more than half of his time to work not solely in the interest of the Museum . It requires no exaggeratio n to show that the number of Curators is wholly inadequate if the present collections and the depart ments now without Curators are to be efficiently cared for and o o for devel ped . The most urgent needs are active Curat rs ' M ollu sca Cru stacea o . , , and Vertebrate Palae ntology The disadvantages under which much of the curatorial work is f on o to o o . carried , wing lack room and equipment , is also depl rable To note specifically a single instance : the collectio n Of inverte brate fo ssils was co nsidered twenty or more years ago to be well A provided for a normal increase and development . ppointed 1 12 o o 9 . o Curat r in , Profess r P E Raym nd has by his knowledge, o field- o S O persistence , and in great measure by his pers nal w rk , increased the collection that four large rooms are o vercrowded o with classified material awaiting distributi n , and large accumula . o not o tions as yet unstudied These additi ns are duplicati ns , but are in large part fro m faunas unrepresented or poorly represented r o o in p evi usly acquired c llections . The same condition prevails with the collectio ns of lower verte of . brates , birds , mammals, and with many groups invertebrates As o of n ted several years ago , the only betterment Museum research facilities involves the eliminatio n or further curtailment of laboratory work in the Museum ; a realiz atio n Of the former would lessen the natural anxiety felt for the safe preservatio n of o o o o absolutely irreplaceable collecti ns , c llecti ns that sh uld be free - from the dangers unavoidable with present day experimental work . 4 ANNUAL REPORT OF T HE l Professor Raymond has continued his successful field-work in New England and Canada ; he secured large series of fo ssils of the o o of Silurian , Ordovician , and Cambrian peri ds ; s me these pro ve o o t be undescribed , very many are rare and new t the Museum o . o o collecti n An Opp rtune disc very at Waterville , Maine , shows that the shales are of Middle Silurian age . Professors Charles ’ S ch u ch ert and E . H . Perkins fu rthered Professor Raymond s work . o hr During a brief stay in Bermuda , Mr Sayles f und t ee fossil $ o o in soils , his preliminary study c nvincing him that they rec rd er lacial o o t g episodes of the Pleist cene peri d , but that a definite o o l - conclusi n can be made nly after additional fie d work . In o Bermuda and in the subsequent study of the material c llected , n ‘ . o Mr . Sayles had the assista ce of Dr T H . Clark . At Ing nish , . o of C o o Cape Breton , Mr Sayles found s me beds arb nifer us age that suggested a glacial origin . o S o o Janu ar — Dr .

Banks also c llected insects and ar chnids, fully $ fl o o o specimens , during June and July , chie y on Barr C lorad Z k . ete Island . Messrs . J B . Shropshire and James , residents at o Z o Anc n , were most helpful in the work in the Canal ne , and we have to thank the United Fruit C ompany for many co urtesies received fro m its Officials . for of Dr .
