As it respects fall or spring wheat, no positive directions can be given, adapted to all climates. In many localities it is of little use to sow winter wheat, as it is very uncertain. In other localities winter wheat almost always succeeds best. This question then must be determined by circumstances. The time of sowing winter wheat varies in different climates, according as it may be exposed to depredations of worms and insects in the fall. Farmers are not liable to mistake in this matter. Spring wheat, in all climates, should be sowed very early. It is hardly possible in all the Middle and Northern states to prepare the ground in spring, and get in wheat in suitable season. The yield of a crop of spring wheat, depends materially upon the growth in the cool and moist weather of spring, when it spreads and its roots get a strong hold before the hot weather, that hurries up the stalks and ears to maturity. Hence plow in the fall, and harrow in the wheat, as early as possible, in the spring. _The varieties_ of wheat are numerous and uncertain. In the state of Maine, an intelligent cultivator, in 1856, recommended Java wheat as having a very stiff straw, and producing a very heavy yield. The Mediterranean wheat is also a favorite variety. Club wheat has also had a great run, and is now very popular at the West. But of varieties no one can be confident. We notice in the discussions of the best agriculturists of England and Scotland, that they have doubts of the proper names of some of the best varieties. In a certain rich part of Illinois we know an unusually popular wheat, sold at high prices for seed, under the name of _mud club_, as being much better than the ordinary club. We happened to learn that it was nothing but common club wheat, sown on rather low ground, where it happened to grow very fair that season. It is only occasionally that such tricks are successfully played, but it is true that many varieties are the result of extra good or chance cultivation. The celebrated Chidham wheat, named from a place where it was successfully grown, was also called Hedge wheat, because a head found growing in a hedge was supposed to be the origin of it. Now it is not probable that that head was the only one of the kind in all the country, and it would by no means be identified in all localities. And as all wheat is the result of the cultivation of the Ægilops or some other wild grass, it shows us that varieties may be produced by cultivation. Great importance is therefore to be attached to frequently changing seed; especially bringing it from colder into warmer climates, and changing from one soil to a very different one. Thus seed raised on hard hills is highly valuable for alluvial soils. Thus the efforts to introduce so many new varieties from the dominions of the sultan, will prove of vast advantage to wheat culture in America. So let us be constantly importing the best from Great Britain and the British
