owners of the pond, these tront were not (hsturl)e(l, althongh 

 it is doubtful whether their spawn would ever amount to any- 

 thing deposited in such a stream. The discovery was occasioned 

 by the fact that the trout had stopped running in the stream in 

 which the trap was located, the inference being that they had 

 learned of tfieir danger and sought new spawning grounds. 

 Whether such is the actual case, cannot be decided until after 

 another season's work. The pond from which these trout 

 ascended into the trap is an ordinary mill pond of about forty 

 acres, used to float logs into a mill, and with no screen at its out- 

 let. The trout average al)OUt tive to the pound, antl the females 

 of this size yield an average of 560 eggs. About 1,000,000 eggs 

 were taken here, a part of wdiich were eyed in a tent supplied 

 with water from an adjacent spring, a part being transported to 

 the St. Johnsl)ury station as soon as stripped. In connectiori 

 with a collecting station distant from the hatchery, it is advisable 

 to have a few troughs set up for eving the eggs before transpor- 

 tation, if suitable water can be obtained for the purpose. The 

 natural brook water is ordinarily of low temperature and too 

 full of sediment to warrant using it for such temporary work. 

 If an adjacent spring is available, troughs can be set up in a tent 

 or shanty and the eggs thus eyed in from thirty to forty days 

 before the most severe winter weather sets in. For this work I 

 use deep troughs and stack the trays ten deep. The first stri])- 

 ping of eggs occm-red Scptemlier 26th, when 66,000 were taken. 

 The second and largest strip])ing occiu'red October 7th, when 

 nearly 500,000 eggs were taken, and the trout had all l)een 

 stripped and liberated on' November 7th. During the season 

 onl\- eighteen trout died. The cost of o])erating this station dur- 

 ing the season, including team hire and transportation of eggs 

 to St. Johnsbury station, was $256.83, exclusive of services of one 

 regular station employe tw'O months. This cost included the 

 cost of construction of trap and shanty, some of which would 

 not enter into the expense of another season. For this privilege 

 of taking trout liberal returns are made to the waters in fry. 



Lake and Pond Spawners. — The method of taking trout from 

 spawning beds in ponds dithers materially from the method just 

 described. The following is a description of a field station and 

 methods of operation where the trout spawn in the lake: 



One of the first important features is to have suitable retain- 

 ing pens in the lake where the trout will be undisturbed and se- 

 cure from poachers. I am describing a station at a lake of 1,500 

 acres area, subject to high winds and rough water. The first
