In November 60,000 eggs were collected from the two-year-old trout 

 reared at the station, and two consignments, comprising 100,000, were 

 shipped from Leadville. The first of these arrived in fair condition, 

 but the last were of poor quality and the losses consequently heavy. 



At the close of the year there were on hand the following fish :

Baird Station, California (G. H. Lambson, Superintendent). 



During June the racks were put in by the regular employees of the 

 station, but it was noted that the number of salmon in the pool was 

 much smaller than in past years. The equipment for the new hatch- 

 ery, which had been completed just before the close of the fiscal year, 

 was installed during the summer and consists of 86 troughs, arranged 

 in sections of eight, so that the water from each gate of the supply- 

 trough passes through four troughs of eggs, with a fall of about 9 

 inches. The upper troughs are 52 inches above the floor and are pro- 

 vided with platforms for the pickers to stand on; the lower troughs 

 are 20 inches above the floor. The troughs are 15 feet 6^ inches long, 

 15f inches wide, and 7^ inches deep, inside measurement, and are 

 equipped with 6 baskets each, 24 inches long, 15 inches wide, and GJ 

 inches deep. These baskets are of galvanized- wire cloth, 5 wires to 

 the inch, f-inch mesh, and are substantially made, the corners being- 

 soldered to an L strip of galvanized sheet iron extending seven-six- 

 teenths of an inch on each side, and the wire cloth attached at the 

 top to the wooden frame by double-pointed tacks. The compart- 

 ments in which they are placed are 25 inches long and are separated 

 by pairs of steel plates placed 1^ inches apart. The first division 

 plate is 12 inches from the upper end of the trough and the lowest 

 division 14 inches from the lower end. The troughs are fastened 

 together in pairs by two iron braces made of f-inch by 1-inch iron, 

 which extend across the bottom and up the sides in the shape of a 

 double L, and are attached by screws. This arrangement leaves the 

 top of the trough open, with no braces in sight, and, moreover, allows 

 the baskets to be shifted without being lifted from the water. 



The water supply for the station, which had been very unsatisfac- 

 tory in the past two years, was increased by the installation of a No. 

 4 Byron Jackson centrifugal pump, geared to supply about 450 gal- 

 lons per minute. The power for operating this pump is furnished by 

 an undershot water-wheel, designed by Mr. Lero}^ Ledgerwood, one 

 of the regular laborers at the station. It is 13 feet long with a radius
