siderably, assumed such proportions that the irrigation of 
a considerable area was effected by it, besides supplying 
the mili 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 mule aveorcaves 
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-
