siderably, assumed such proportions that the irrigation of 

 a considerable area was effected by it, besides supplying 

 the mill with abundance of water. As regards the ever- 

 green trees, the first cultivation of barren ranges or high 

 plateaus might advantageously be undertaken with these 

 on account of their ability to resist the severity of the 

 climate in those exposed localities, and to grow on stony 

 and poor soil. But even on rocky ground and in high 

 altitudes the larches, birches, and other deciduous trees 

 will often do well and serve better for the end which we 

 have in view, the water storage and the pisciculture. 



In such localities, where only the most hardy trees can 

 be reared, it would be practical to cultivate along the 

 watercourses, in the valleys and ravines, or any lower 

 ground, a few rows of deciduous trees as soon as the other 

 trees had attained sufficient height to protect them from 

 the storms and the frosts. Several objects may be gained 

 by doing so. First, the shade, shelter, and other beneficial 

 effects for the fishes ; secondly, that more valuable timber 

 could be reared, as these trees have, as a rule, a greater 

 preference for damp and moist localities than the ever- 

 greens ; and, thirdly, because the deciduous trees permit 

 more freely a luxuriant undergrowth of shrubs and annuals. 

 All freshwater fishermen will agree with me in the advan- 

 tage of having a good growth of annuals as watercresses, 

 nettles, &c., near the bank, and have observed that during 

 feeding time the fish always seek such places. There 

 is a vast variety of shrubs and annuals, that might easily 

 and with great advantage be introduced and grown on 

 the river banks, but it would be outside the bounds of 

 this paper to enter fully on the theme. However, I may 

 only mention that many fodder plants and grasses from 

 other countries might be a source of wealth to the popu-
