33O MARINE BIOLOGICAL LABORATORY. 



The equipment of the new laboratory has been provided for 

 by an additional gift from Mr. Crane, and the executive officers 

 have proceeded with the necessary plans in order to avoid delay 

 in the opening of the building. The most important part of the 

 preparation, viz: provision for adequate pumping facilities, is 

 completely arranged for. It involves construction of a wharf 

 on the harbor front to carry a supply pipe out to deep water, but 

 also useful for other laboratory purposes, and the installation of 

 pumps and the power plant. After considerable inquiry we 

 decided on hard rubber pumps of such construction that no 

 metal can come in contact with the sea-water. We believe that 

 all sources of metal contamination of the sea-water in the system 

 of pumping and distribution have been avoided. The valves 

 in the system are of special lead, manufactured by the Crane 

 Valve Company, thus avoiding a source of metal contamination 

 in the use of brass or bronze valves. The power will be furnished 

 by electric motors with a reserve gasoline engine. Other details 

 of equipment need not be included in this report. 



At the last meeting of the board of trustees the director and 

 assistant director were authorized to proceed with plans for the 

 improvement of the water front. Surveys were accordingly 

 made, and plans prepared for the erection of sea-walls both on 

 the harbor and eel-pond frontage; wharves in connection with 

 these improvement were also planned, and filling and grading 

 in order to utilize the space in the best possible way. Such part 

 of these plans as required state permits were presented to the 

 harbor and land commission of the state of Massachusetts and 

 the permits secured. The drawings of these projects are here- 

 with presented. 



It is not necessary to proceed with all of this work at once; 

 but it is essential that anything undertaken should be part of 

 a general plan, and this is the idea we have had in mind in plan- 

 ning so much at once. 



We still have before us the necessity of an endowment before 

 we can feel certain that the operation of the Laboratory can be 

 continued uninterruptedly. The estimates for the year 1914 

 show a probable deficit of about $20,000, a very small sum con- 

 sidering the magnitude and significance of our operations. An
