One of the most interesting movements in agricultural education has been an attempt to introduce nature-study and even the elements of agriculture into the country schools. Cornell University has taken the lead in advocating "nature-study" purely, for the schools; and the University of Missouri has perhaps been the leader in advocating that the work be made even more definite and practical, and that the country pupils shall be taught, during their early years even, "the elements of agriculture." Both plans are being worked out with a fair degree of success, and many other states are carrying out the work in some form or other. Of course the idea is not a new one, but its present practical application is a timely one, and it will not be long before this branch of agricultural education will become a prominent factor in rural betterment. A most suggestive phase of agricultural education is college extension work. University extension has had a rather meteoric career in this country, in so far as it has been connected with educational institutions; although the extension idea is spreading rapidly and is being worked out through home study and correspondence courses of all sorts. But I think there is scarcely any field in which the real college extension idea is today being more successfully applied than in agriculture. The work started with farmers' institutes, which were instituted about twenty-five years ago and which have been adopted in practically all the states of the Union. It has broadened within ten years, until now it is carried on not only by farmers' institutes, but through home-correspondence courses, the introduction of millions of pamphlets into farm homes, demonstrations in spraying, butter-making, soil testing, milk testing, and so on. Ontario presents a good illustration of how a new agriculture can be created, in a dozen years, by co-operating methods of agricultural education. Her provincial department of agriculture, her experiment station, her agricultural college, her various forms of extension work, and her various societies of agriculturists have all worked together with an unusual degree of harmony for the deliberate purpose of inducing Canadian agriculturists to produce the things that will bring the most profit. The results have been most astonishing and most gratifying.
