pL 11] POND-CULTIVATION ON THE KANIOW ESTATE. 543 
most practical farmers have, as a general rule, been but little benefited 
by the grand results of scientific investigation, and that, unfortunately, 
they lack a thorough knowledge of the aquatic fauna which is of such 
great importance for the feeding of fish. In the interest of pisciculture 
I herewith express the justified wish that scientists may give us still 
more practical advice. By carefully raising the respective aquatic 
animaleulz for fish-food, we should, perhaps, sueceed in favoring the 
growth of the fish during the second and third year in a similar way as 
is done during the first year. 
I cannot too strongly urge all farmers who take an interest in pond- 
cultivation to make—in their respective localities—further observations 
and experiments relative thereto, and I sincerely hope that their expe- 
rience will be published for the general good. It is one of the beauties 
of agriculture, that it knows no professional envy, and dare not know 
any, for even if the greater experience of one man benefits another, the 
first one will not deem his interests endangered thereby, since a larger 
production, by creating a greater demand and better markets, will in the 
end again prove a benefit to him. 
As far as Tam concerned, I shall also in the future gladly make known 
to the general public the results of any further experiments in pond- 
cultivation. I shall rejoice at every success obtained by other farmers 
and pisciculturists, and in anticipation of such happy results I herewith 
hid them, from the depth of my heart, a sincere God-speed.
