192 THE SCIENTIFIC ANGLER. 



the still deeps and slow-running streams; but eddies, 

 small holes, and rapid running streams, are the best 

 places to fish. Should, however, a strong breeze dis- 

 turb the surface of the water, the angler may pursue his 

 sport on the smoother reaches. Foster's intermediate 

 will be found very effective when duns are on the water. 

 This is a copy of all the duns prior to their re-appearance 

 as spinners. It is well known that fish invariably seize 

 sickly or maimed insects, or small fry, etc., from the 

 midst of their more lively companions. The Sand fly 

 is the color of reddish sand; it is a flat-winged fly, and 

 is very plentiful in this month and the next, and is a 

 good killer when there is no quantity of any particular 

 flies on the water. 



The Stone fly is a flat-winged fly; the wings and body 

 are of a dark stone color, the latter is strongly marked 

 with yellow ribs; the legs are of a greenish brown, and 

 these it uses with extreme activity. When not on the 

 water it frequents stones and pebbles by the sides of 

 streams, on the rapid parts of which the artificial should 

 be used. Many fish are taken by dibbling with the natu- 

 ral fly near the roots of overhanging bushes. It resem- 

 bles a beetle in its flight, falls very heavy on the water, 

 and is a substantial bait for large fish. On some streams 

 it is known as the May-fly, as the green drake does not 

 appear on those waters. It is a water-fly, and lasts from 

 the beginning of April to the middle of June. 



The Grannum, or Green-tail, makes its appearance in 

 this month. This is a flat-winged fly, of the size and 

 shape of the Sand fly, with the addition of a green ap- 

 pendage at the end of the body, which is its egg-pouch. 

 This fly is quite a favorite with fishermen in April, but 

 we confess we have seldom done much with it until the 

 latter part of summer.
