Kindly obtain for me any information available from ary 
sources which you may have as to the highest speed at which it is safely 
possible to haul in a dredge containing live organisms* That is^ the 
feet per minute* In designing the winch, I had in mi ind not exceeding 
130 feet per minute* However, this may be too fast* 
Further, any information from actual experience by 
expeditions in the east as to the method of caring for the cable, regarding 
salt Water, would be acceptable* Of course I have the local information, 
but w’ould like to obtain everything frmi all sources, using only the best. 
Information as to the most desirable weight of dredge 
for 100 fathoms would be helpful* 
In coiTiinuni eating with the three scientists, and with

dredge, of coiirse, at depths, but what has been their most successful 
type of dredge?
