But this is not all. The mutual consultation and discussion consequent upon Agricultural Fairs, begets a spirit of inquiry and a desire for information in relation to every subject connected with the farmer's calling, and to gratify which he has recourse to periodicals and other works in which its various branches are discussed and explained. He will there learn what agricultural chemistry has done for him, and the importance and value of the analysis of the different kinds of soil. He will also find the result of the various systems of husbandry practiced by others as well as the effects of experiments made, and thereby secure to himself their benefits without incurring their cost. And although no amount of reading alone can make a man a farmer, yet the knowledge derived from a perusal of agricultural papers devoted to the interests of the tillers of the soil will be of incalculable value to him. SHEEP-HUSBANDRY. It will undoubtedly be expected that "Sheep-Husbandry," not only from the importance of the subject itself, but because of its being the principal feature in this exhibition, should receive at my hands a due share of consideration. I am free to confess, however, that the subject will be approached with no small degree of hesitancy and distrust on my part, not only because of my want of practical knowledge in regard to it, but also because it may be fairly regarded, I think, in many respects at least, as a sort of debatable ground. Different views are undoubtedly entertained by equally intelligent and experienced men, upon this as well as upon other equally important subjects; and the fact I believe is well established that "Doctors" not only _may_ but _do_ very often "disagree," and that, too, sometimes very tenaciously. Should I advance opinions at variance with those entertained by well-informed and practical men who may listen to me, I will simply remark that I am not here to lay down rules and establish principles for the guidance of any one, but to discuss principles and rules of action, as well as practical questions, with a view to lead others the more carefully to inquire into and investigate the same. The subject of Sheep-Husbandry with us is certainly an important one--wool being a great, leading staple product of our State; and very much attention is now being paid to it, which is fully justified by the advantages of our soil and climate for the keeping of sheep. The farmers of Michigan are fully aroused to the importance of this interest, and have labored zealously, and at much expense and cost, to improve their breeds of sheep, and to foster and develop this great interest. They have certainly done much in this direction; but more--very much more, I apprehend--remains yet to be done. It must, however, be remembered that a blind zeal, without that knowledge which is the result of experience, observation and study, will do very little in the right direction.
