While it will be Mr. Y.'s care to direct the attention of the pupils to chemistry and geology in their application to practical agriculture, a branch of study until lately very little attended to, he will make arrangements for procuring the services of the professor of agriculture in the University of Aberdeen, for a few weeks every summer, to give lectures and conduct experiments on the analysis of soils, manures, &c.--thus securing to the pupils more than a mere theoretical knowledge of this important branch of agricultural education. As nothing is so much calculated to impress any subject upon the youthful mind, as to invest it with a _personal interest_, Mr. Y. proposes to devote to the exclusive use of his pupils, a small farm, of about 50 acres in extent, adjoining to his other farm. This small farm contains a variety of soils, upon which experiments of different kinds may be conducted, on a small scale. It will be possessed and managed by the pupils, under Mr. Y.'s direction, and upon certain equitable rules as to each pupil's share of the concern. Each pupil will be required to keep regular books, exhibiting all disbursements and receipts, and the results of all experiments tried, with every particular connected with such experiments. Each pupil will be required to take his share of management, &c., and the profits of the concern, after paying a certain moderate rent, will, at each term, be divided among the young gentlemen, in proportion to their respective interests. It is conceived that such a plan will have a strong tendency to promote exactness, regularity, and business habits; but, without the consent of their parents or guardians, pupils will not be asked to join in this scheme.
