a different character should occupy the ground in rotation, that the soil may be kept in the richest state. Thus the quality or size of the crop will not be lessened by being planted in a situation that it has depleted, to some extent, of its own particular food the year before. Reference should also be had to the kind of food which the plant requires, as in the case of strawberries and potatoes, which should not succeed each other without special manures, as they both exhaust, to a great extent, the potash in the soil, so that the soil, haying borne a heavy crop of one, would of necessity make but a poor return of the other if planted in direct succession. If this cannot be overcome by a change of location, the gardener will know that the proper food elements have been depleted by the previous crop, and must try to supply them with special manure or commercial fertilizers.
It is of great importance to rapid work and good gardening that all this should be arranged and settled in the gardener’s mind, or better, plotted out on paper, before the first plowing is done in the spring. The plan being kept would be valuable in laying out the garden the succeeding year, as it would show just where each vegetable had been grown and where the different kinds of manure had been applied. If, in addition, the success of the various crops and notes of their growth were marked upon it, it would form a most valuable text-book for the study of improved gardening, each garden being an experimental station and each gardener a student in pursuit of knowledge and advancement in his
