It is but a comparatively short time since that article was written, and yet the spread of sound opinion, of correct and enlightened views, and of a just appreciation, as well of the aids which science is capable of giving to agriculture, as of the expediency of availing ourselves of all these aids, which within that period has taken place among practical men, has really surprised us. Nor have we been less delighted by the zeal with which the pursuit of scientific knowledge, in its relations to agriculture, has been entered upon in every part of the empire--by the progress which has been made in the acquisition of this knowledge--and by the numerous applications already visible of the important principles and suggestions embodied in the works then before us, (JOHNSTON's _Lectures and Elements of Agricultural Chemistry and Geology_.) But on this important topic we do not at present dwell. We may have occasion to return to the subject in a future number, and in the mean time we refer our readers to the remarks contained in our previous article. The truly scientific man--among those, we mean, who devote themselves to such studies as are susceptible of important applications to the affairs and pursuits of daily life--the truly scientific man does not despise the _practice_ of any art, in which he sees the principles he investigates embodied and made useful in promoting the welfare of his fellow-men. He does not even undervalue it--he rather upholds and magnifies its importance, as the agent or means by which his greatest and best discoveries can be made to subserve their greatest and most beneficent end. In him this may possibly arise from no unusual liberality of mind; it may spring from a selfish desire to see the principles he has established or made his own carried out to their legitimate extent, and their value established and acknowledged--_for it is the application of a principle that imparts to it its highest value_. [Footnote 1: THE BOOK OF THE FARM. By Henry Stephens.] Science is to practical skill in the arts of life as the soul is to the body. They are united as faith and works are in concerns of higher moment. As both, though separately good, must yet be united in the finished Christian, so the perfection of husbandry implies the union of all the lights of existing theoretical knowledge with all the skill of the most improved agricultural practice.
