XXVIII REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



questions in future, Mr. von Bayer was directed to prepare a set of 

 plans which combine the most important principles of fishways, and 

 which can be easily adapted to the various constructions of dams. 

 These plans, with directions for practical use, are completed and are 

 ready for distribution to any State officer or other responsible person. 

 A copy of this plan on a small scale is shown on plate iii. 



In addition to the regular duties of the naval engineer, he has pre- 

 pared plans for new boilers for the steamer Albatross, and for the 

 electrical and refrigerating apparatus at the Omaha Exhibition. Past 

 Assistant Engineer C. W. Dyson, U. S. N., who has efficiently filled this 

 position since October 21, 1895, was detached for regular naval duty 

 April 26, 1898. 



The distributing cars Nos. 1 and 3, having been in almost constant 

 use fifteen years, showed the effects of continued service, and $10,000 

 having been appropriated, they were rebuilt and i)laced in thorough 

 repair during the fall of 1898. They were supplied with modern equip- 

 ment, and modifications suggested by experience were made in their 

 arrangement and appliances, increasing their capacity and enhancing 

 their strength and usefulness. 



On account of the growth of the business of the Commission on the 

 Pacific Coast and the consequent continued presence there of field 

 agents and other employees, it became advisable to provide suitable 

 office accommodations, as well as storage room for the material, which, 

 in the form of collections, equipment, etc., had accumulated in consid- 

 erable quantities. As no quarters were available in the Government 

 Building in San Francisco, a room in the Academy of Sciences Building 

 in that city was engaged at nominal cost, and has been of value in the 

 convenient and i>rompt transaction of business in the West, especially 

 in the preparation and distribution of reports relating particularly to 

 the Pacific States. 



During the year the bound reports, with appendices, for the fiscal 

 years 1896 and 1897 and the following pamphlets were issued :
