One feature may appear, to some investigators, a serious drawback, 

 and that is the lack of running water. The experience, however, of 

 those who have carried on protracted series of experiments involving 

 the keeping of living material throughout the season has been that no 

 inconvenience has been felt by the absence of running water. The 

 main reason for this is that the temperature is so low that one may keep 

 material standing in dishes in the laboratory for many days without 

 even changing the water. Thus one may keep hydroids, echinoderms, 

 and even the " candles " of dog-fish without difhcultv. 



The laboratory is supplied with several small boats and with a motor 

 boat, similar to the one which is used by the fishermen of Casco Bay. 

 It is wonderfully seaworthy and safe, and for the collector it is ideal. 

 If occasion demands, additional motors may be rented at low fees by the 

 day or week from the fishermen. An ample supply of seines, dredges 

 and trawls is maintained at the laboratory. The stock of chemicals 

 and reagents is large, and whenever additional supplies of this char- 

 acter are required they are readily obtained from the larger dealers of 

 Portland, who keep constantly on hand all but the more exceptional 

 reagents. In fact, this city may be drawn upon for supplies rarely 

 found in other cities of its size. 



Accessibility to the laboratory is assured. The city of Portland is the 

 terminus of the Grand Trunk System, and of the Boston and Maine 

 and Maine Central railwavs and of several coastwise lines. The Maine
