10 BULLETIN OF THE UNITED STATES FISH COMMISSION. 



4. — What time are Salmo fontinalis caught by angling? 



A. — Salvelinus fontinalis can be caught by angling in the latitude of 

 New York City from about the 1st of April to about the 1st of October, 

 though I believe the close season begins somewhat before October 1. 

 Before about the 1st of April the water is usually so cold that the trout 

 do not feel much like bitiug, and after the 1st of October the spawning 

 season is so near that they do not care then much about bait or any 

 food. As one goes farther north the season for angling begins later and 

 ends earlier. Trout are not found much south of the latitude of New 

 York City, except at high levels. 



5.— With what fly or bait? 



A. — Trout fishing in this country is done mostly with artificial flies. 

 The different varieties of flies used are innumerable. Those which are 

 considered the most effective, taking the season through, are perhaps 

 the "Professor," "Montreal," "Jenny Lind," "Coachman," "Black 

 Gnat," and " Cowduug." When bait is used the common angle worm 

 is the favorite lure for trout, but grasshoppers, various flies and insects, 

 and particularly the grub worm, are used at different seasons and in 

 various localities with good results. Salmon spawn also makes a good 

 bait when it can be procured. 



6. — Do they spawn also in lakes like other Salvelinus, or only in riv- 

 ulets like Truttafario ? What mouths ? 



A. — Atlantic coast trout, like Trutta fario, spawn almost exclusively 

 in brooks and rivulets, and manifest a strong impulse to ascend the 

 streams to a considerable distance. When, however, they cannot do 

 better, they will, like other charrs, spawn on the shores of lakes, always 

 seeking either a springy spot or a clean gravelly one, or both. Their 

 spawning months vary very much, probably according to the tempera- 

 ture of the water. At the Cold Spring trout ponds, at Charlestown, 

 X. H., the trout almost invariably begin to spawn the second week in 

 October, and end before Christmas. Farther north in ordinary brooks 

 they spawn earlier. Farther south they spawn somewhat later, and in 

 ponds or streams which are fed by springs large enough to keep the 

 water of very even temperature through the cold months, the trout 

 spawn from the 1st of November till some time in April. 



7. — Are they thought good for pond culture ? 



A. — In America, Salvelinus fontinalis takes the first rank as a fish to 

 be cultivated in ponds, provided the ponds are fed by springs or cold 

 running water. Ponds not possessing these qualities are unsuitable for 

 brook trout. 



8. — There seem to be different kinds of Salmo fontinalis in United 

 States, for when some time ago I received a box of eggs, which were 

 first cabled as lake trout, but afterwards declared by you to be broolc 

 trout (Salmo fontinalis), you especially remarked that these Salmo 

 fontinalis eggs were of a special excellent variety, and my German
