Meantime Ohio has at least once gone down to four bushels 
per acre, and her agricultural leaders are very properly sound¬ 
ing the alarm. With such facts as these before us, it is use¬ 
less for the wheat-growers of Wisconsin to close their eyes to 
the fact that our soil is fast being exhausted of its wheat ele¬ 
ments ; so that, with the present low prices, wheat-growing must 
have resulted in the loss of several million dollars, besides the 
exhaustion of the soil. 
' RESTORATION BY ROTATION OP CROPS. 
In seeding with tame grass, it is advisable to use clover and 
timothy mixed ; for while timothy grass is not a renovator of 
soil it improves the quality of the. hay and helps the clover to 
stand up. One-third clover and two-thirds timothy seed makes 
a good mixture for meadow, and on very dry or worn land 
one-half clover would be better, while for pasture it is best to 
use two-thirds clover because of its renovating power; its long 
tap root drawing nourishment from the subsoil, while its im¬ 
mense foliage assists in supplying nitrogen for plant food. 
Experience proves that it is not advisable to continue a field 
in grass longer than three years. When the farm is so fenced 
as to admit of pasturing the land, it is decidedly preferable to 
pasture it the last year or two of the three. The greatest 
amount of hay and pasture can be obtained from the land 
when this plan is pursued. 
The land should be manured and spring-plowed and planted 
to corn the fourth year, and the corn well tilled so as to leave 
the land clean for the crop of wheat that is to follow. The 
land should be plowed in the fall for wheat, as the difference 
of a few days, in the spring, in the time of sowing will often 
cause a loss of one-fourth or one-third of the crop. Fall plow¬ 
ing is the most productive, if the sowing is done at the same 
time ; and if the land is not the best of wheat land, and in the 
highest state ctf fertility, it should be seeded down to grass 
again. But if the land is in a high condition and a good 
wheat soil, a second crop of wheat may be taken before seed¬ 
ing to grass again. But when our agriculture shall become
