only as regards freshwater fishing can this be said. In 
Denmark it is a well-known fact that the best fishing is 
where a forest is close to the shore, and in particular where 
the trees, as is often the case in that country, overhang the 
very sea. The shadowing trees have another and, perhaps, 
the far more important effect of preventing a large evapora- 
tion, and at the same time keeping the water clear and cool 
in summer, while on the same account the winter frosts do 
not deal so severely with them. In all forest country the 
changes of temperature are not so severely felt as in a 
treeless country or on the open plains, and the effect upon 
the water is even greater. It is a popular saying in 
Denmark of the forest streams, that they are cool in the 
summer and warm in the winter, this, of course, meaning 
that they present that feeling in comparison to the atmos- 
phere. The forests not only regulate the flow of the water, 
but they purify the water. This is an experience often 
demonstrated in Australia in cases where streams have 
been polluted by wool-washing establishments. After 
having passed a few miles through a shady and dense 
forest the water will appear as clear and pure as it was 
above the woolwash. 
I need not here enter upon more reasons for the con- 
servation of existing forests to ensure a steady supply or to 
draw your attention to the danger in not protecting them 
by legislation. But I will draw your attention to the ad- 
visability of cultivating forests on places suitable for the 
supply of water, and especially along watercourses and 
lakes as means of purifying these, preventing too great 
evaporation, supplying food for fish, and providing these 
with shade against the rays of the summer sun, and shelter 
from the pelting rains, the hail and the tempests.
