lation, and greatly benefit the fish as well as the owners 
of the land, if cultivated on the banks. The Prickly Com- 
frey, e.g. (Symphytum asperrimum), which yields such a 
splendid forage by its abundant foliage, and many others, 
are easily reared both from seed and cuttings, and should 
do well in the low lands, while on the sandy beaches, near 
the outlet of rivers and creeks, the cabbage radish (Pringlea 
antiscorbutica) would cover these barren and desolate places 
with vegetation, and furnish an object of merchandise by 
packing them for the use of fishermen and sailors in the 
Arctic regions. The plant when cooked is a good sub- 
stitute for cabbage, and has a most wholesome effect on 
persons suffering from scorbutica. 
By a judicious forest management, which I will not 
enter upon here, the land can be kept covered constantly, 
and always in a state favourable to the purpose of storing 
the water. That many of the evergreen trees may be of 
great importance, and particularly where they are better 
suited to clime and soil, I will not deny. The Australian 
eucalypts, which have such a beneficial effect on the health 
of man, may also serve well for pisciculture, but as far as 
I know, no experience is yet at hand with regard to this. 
Still I doubt if these trees might not do more harm than 
good by being planted on watercourses, on account of their 
great drying properties. In warmer countries, the place for 
these trees is where stagnant waters during summer are 
breeding places for fever and ague. The cultivation of the 
borders of watercourses has also a great significance to us, 
and it is here that the deciduous trees must be mainly 
utilised. The belt need not be very broad, say half a chain 
wide, and planted with good-sized plants at the rate of 
from 800 to 2000 per acre, according to their age. Even 
a double row of trees would be a benefit, but it is important
