REPORT OF COMMISSIONER OF FISH AND FISHERIES. 47 



A consigument of 11),000 You Belir trout eggs, received from North- 

 villo February 5, 1891, jiroduced satisfactorily, tliere being more tlian 

 17,000 fry on hand April 1. A second consignment of 0,900 eggs from 

 the same source also produced well, there being 5,500 I'ry on liandMay 

 11. These, in addition to the 17,000, were retained for rearing. 



Vigilance was required to protect the stock offish against predatory 

 animals, and during the year there were killed lOS birds, 21 mammals, 

 and 98 reptiles, not including frogs. 



In addition to the constiuctions provided under the si^ecific appro- 

 priations before mentioned, there was built, for the use of the Ooni- 

 niissiou's distributing cars, a siding from the Kansas City, Fort Smith 

 and Southern Railway. A connection was also made with the water 

 main of Neosho for supplying the station, as well as the distribution 

 cars while occupying the railway siding.

tendp:nts). 



In the report for 1888 mention was nuide of the locatioji of a station 

 near Leadville, Colo., for the breeding and roaring of trout, and of the 

 apx)ropriation by Congress of $15,000 for the necessary constructions. 

 As soon as this sum became available, Jidy 1, 1880, plans and specifi- 

 cations for a fish-hatchery w(?re pre})ared and proposals for its erection 

 invited by advertisement. But one bid being received, and that for a 

 sum greater than the appropriation, a second call was made, resulting 

 in the receipt of three bids, the lowest being that of Mr. L. G. Hunt, 

 of Pueblo, Colo., at $12,672. This was accepted, and on October 11, 

 1889, formal contract for the construction of the building was made. 

 Work was immediately begun, but owing to many causes, chiefly bad 

 weather and roads, the building was not completed till October, 1890, 

 final acceptance of the structure not being given till November 1. 



In view of the failure to receive suitable proposals in response to the 

 first call, and the delay that woTild ensue before new proposals could 

 be obtained and the contract let, which would liave resulted in the loss 

 of a year's time in the active work of propagation, it Avas decided to 

 erect a frame building which could ])e used as a temi)orary hatchery 

 and afterw^ard as a rearing-house for fry. A box flume, some 740 feet 

 in length, was laid to bring, by gravity, from springs on the hillside, a 

 supply of water to the hatchery. Active work was commenced on Sei>- 

 tember 9, 1880, and the structure was ready for the recei)tion t»f eggs 

 about the middle of October. In the meantime, by permission of tlie 

 owner. Dr. John Law, 8,000 brook trout were taken from the Evergreen 

 Lakes and held in ponds till ready to spawn. From these fish 508,000 

 eggs were obtained and jilaced in troughs in the temporary hatchery. 

 The erection of this temporary hatchery was under tlie general direc- 

 tion of Mr. John Gay, iuspe(;tor of statiouSj assisted by Mr. William
