care in selection, but because the wool of the original flock is in demand, 
it is necessary to keep as nearly similar to it as possible; but as this is 
fighting against nature, it is more costly to produce on equal land values, 
and then it is only a relatively good or bad substitute. This applies 
possibly to animals and plants alike. It is nature warring against man 
all the time, and it leads one to think it is better to perfect the strain 
of plant or animal that the environment lends itself to. 
Perfect the Strain Suitable to the Environment. 
Is this not a sufficient reason for wheat-growers to carry out seed 
selection on their own farms, and establish varieties best suited to their 
environment ? 
When wheat-buying is placed on a proper systematic basis, the 
miller can so blend the wheat that the flour may suit every trade, 
whether it be the baker, the pastrycook, biscuit manufacturer, or the 
patent-food maker. 
There is a market for all, and although one class of grain may bring 
the highest price, if grown in the wrong environment it is likely to be 
of poorer milling quality, or less prolific. 
By experiment and selection, a farmer may produce a variety equally 
as valuable as the other, especially if he works in unison with the wheat- 
breeder, who evolves thousands of different seedlings, in order that among 
the many a few new types may be formed of greater merit than existing 
ones. A great advance in this respect has been made during the last 
decade, by the farmers of the Commonwealth, than during the previous 
one.

The man of science has learned to believe in 
justification, not by faith, but by verification.
