62 EEPORT OF THE COMMISSIONER OF FISHERIES. 



received from a number of contractors for the work, but none of a 

 satisfactory nature within the limits of the appropriation were 

 received. 



At the Cape Vincent, N. Y., station there has been satisfactory 

 progress in making the improvements contemplated. The most 

 important items are the general remodeling of the interior of the 

 hatchery building. This involves new windows, floors, and floor 

 joists, the reinforcing of the stone walls of the building, and the 

 general rearrangement of the hatching batteries, pumps and heating 

 plant, all making for economy in space and convenience in opera- 

 tion. A 10-inch suction pipe from the end of the dock to the pumps 

 has been laid and a new pump installed. Concrete piers, to serve as 

 a foundation for an 18,000-gallon Avood-stave tank supported on a 

 steel tower, material for which has been ordered under contract, 

 were in place at the close of the year, and the construction of a white- 

 fish battery of an improved type, together with a building to shelter 

 the fry tanks, was under way. 



The special appropriation of $50,000 for the reconstruction of 

 buildings at the Baker Lake station, which were destroyed by fire 

 on July 21, 1919, became available in November and work was im- 

 mediately undertaken. A new frame hatchery 56 by 130 feet, 

 equipped with 150 standard salmon-hatching troughs with a capacity 

 for at least 40,000,000 sockeye-salmon eggs and fry will be ready for 

 occupancy during the 1920 spawning season. In addition, a tem- 

 porary shelter containing 40 hatching troughs was completed in time 

 to successfully handle the large egg collections made in the fall of 

 1919. All the lumber used has been cut on the grounds by means 

 of a sawmill purchased and installed for the purpose. This mill 

 will be a valuable permanent adjunct to the station. 



The special appropriation for the improvement of the water supply 

 at the Wytheville (Va.) station has been used in the installation 

 of approximately 4,000 feet of 14-inch wood-stave pipe. The work 

 involved the construction of a cement dam in Tates Eun, from which 

 point the water "is taken, the excavation of a ditch 3 feet deep by 

 2 feet wide and 4,000 feet long, 500 feet of which were blasted from 

 solid rock, and the construction of a dam and four bulkheads of 

 cement where the line crosses the creek. The complete installation 

 increases the water supply by approximately 1,500 gallons of water 

 per minute. The laying of "this line necessitated the purchase of a 

 right of way across intervening land. 



The new biological laboratory at Fairport, Iowa, to take the place 

 of the one destroyed by fire, is practically completed and was ready 

 for occupancy in the summer of 1920. The building is of concrete, 

 stone, and brick construction, and is designed to be fireproof. The 

 outside dimensions are 101 feet 8 inches by 54 feet 6 inches. The 

 main floor comprises two office rooms, four biological laboratories, 

 and a chemical laboratory, besides a room of two compartments for 

 embedding and microtome work, a stock room and a museum with 

 adjoining work room. On the second floor are a large and well- 

 lighted library, 2 laboratories, 10 bedchambers, 3 bathrooms, and 

 linen closets. ' The third floor, which is completed only over the 

 center or main portion of the building, comprises 10 rooms which 

 may serve as required for bedchambers, storage, and other appro-
