The great changes which since that day have taken place in the dairying world are due chiefly to a division of labor, the introduction of system and co-operation. Our machinery, we are sorry to say, is not yet quite perfect in all its parts, and does not move with the precision and harmony of the orchestra, to which we have already alluded. Yet, although still in its infancy, it has already produced and does annually produce results grand indeed. If we take a glance at the various industries at which men are to-day engaged, intellectual, commercial, and mechanical, the painstaking exactitude everywhere practiced will be found to be a growing subject of wonder and admiration. The secret of this lies in the fact that perfection in any department of business not only enlarges that business but also enriches those engaged in it. For example: there are perhaps ten times as many watches manufactured in the world to-day as at any other period in its history. It is a profitable business, or men would not engage in it, and the superhuman effort that is being continually put forth to increase the value, by making as perfect an article as human power can produce, establishes conclusively the assertion that there is always a profit in doing well. I am glad to observe that in the cheese industry of the United States and Canada, the light of this truth has to some extent aroused the slumbering dairymen. To quote from the Utica Herald of Sept. 11, 1883: "It is estimated that about 700,000 men are employed in this business, in one capacity or another, and that about 15,000,000 cows are used to furnish the one product of milk. The returns from this product are over $800,000,000. The total amount of capital invested in dairying in the United States is estimated to reach the enormous sum of $2,000,000,000." In consulting these figures we hope there is no person so dense of understanding as to entertain for a moment the idea that had the old system of every man his own cheese-maker prevailed that anything approaching this grand result would ever have been attained. Never. The concert or effort attained in the factory system is the key note to this grand, soul-inspiring chorus.
