DIRECTOR S REPORT. 15 



recommends that none of this land be permanently alienated 

 from the Laboratory by outright sale; and in order that it may 

 be reserved for the purposes for which it was acquired he also 

 recommends that none of it be otherwise disposed of except to 

 members of the Laboratory unless by vote of the Board of Trus- 

 tees in each case. Deeds of sale should, therefore, include a 

 claim ensuring ultimate reversion to the Laboratory on equitable 

 terms, and provisions should also be made for long term lease- 

 holds. The form and value of the leasehold have occasioned 

 much thought, and certain proposals are herewith presented for 

 consideration by the Board. The valuations have been deter- 

 mined with no idea of speculative gain, but solely from the point 

 of view of covering cost and expense of development with a small 

 margin of safety for probable slowness of development. There is 

 room obviously for difference of opinion with reference to values 

 set on individual lots which have been determined as nearly as 

 possible on the basis of general desirability. It will be found on 

 comparison that the values thus determined contrast very favor- 

 ably with the prices of building lots anywhere else in Woods Hole. 

 There is appended as part of this report a list of the staff, 

 of investigators and students in attendance, a tabular view of 

 attendance covering the last five years, a list of subscribing 

 institutions, the Evening Lectures, and the Membership of the 

 Corporation.
