APPENDIX. 273 



The smaller of the two springs which is five feet higher 

 up the hill than the larger, is led off to one side to supply 

 the hatching-house and nursery. After which the water 

 unites with that from the large spring, and flows through 

 two rearing-races into pond No. 1, and then through spawn- 

 ing-races into ponds No. 2 and No. 3. The young trout 

 are kept from the time they leave the nursery and rearing- 

 races until they are about twenty-one months old in pond 

 No. 1. After this age they are to occupy pond No. 2 for 

 a year, and then pond No. 3, from which they are to be 

 taken for market. 



The hatching-house, forty-four feet long and sixteen feet 

 wide, occupies, in part, an excavation made in the side of 

 the hill, and extends out on a sloping lawn. 



The fall from the upper spring is sufficient to allow of 

 the hatching-troughs being elevated three feet above the 

 level of the floor. Thereby saving a great deal of laborious 

 stooping during the hatching-season. The nurseries or 

 rearing-troughs are also elevated, and discharge by minia- 

 ture fish-ways into the rearing-races supplying pond No. 1, 

 which extends on the lawn between the hatching-house and 

 No. 2. The hatching-house is planned for eight troughs, 

 each thirty-two feet long, in case he should require as many. 

 Each trough being divided into twenty nests, and each 

 nest holding four or five thousand eggs, he will be able, if 

 he should find sale for them, to lay down from six to eight 

 hundred thousand eggs every season. 



In the meadow below and in full view from his dwelling- 

 house. Mr. Christie will have a pond or miniature lake of 

 six or eight acres, into which he will discharge all his trout 

 from pond No. 3 that may be unsold at the end of each 

 season, as well as the young fish he may not find sale for. 

 Here, by the time the pond is stocked there will be a great 

 deal of natural food. He will introduce chub, shiners,
