It is no part of our design to go into any general description of agricultural implements. There are constant changes and improvements, and they are introduced at once to the whole country by the inventors or dealers. We also wish to avoid all participation in the controversies respecting the merits of various new inventions. We have several forms of cultivators, horse-hoes, subsoil-plows, drills, seed-sowers, land-diggers, and drainers, various formed plows, root-cleaners, corn-planters, &c., &c. These possess different degrees of merit; all have their day, and will be superseded by others, in the general advancement that marks the science of soil-culture. We strongly recommend the use of the best tools, especially subsoil-plows, seed-planters, and root-cleaners. Always have a tool-house, as much as you do a kitchen. Use the best tools; never lay them down but in their proper place; and always clean them before putting them away. Keep all the wood-work of tools well painted, and the iron and steel in a condition, by the application of oil and otherwise, to prevent rust. Good tools facilitate and cheapen cultivation, and increase the yield of crops, Money paid out for such tools is well expended. TRAINING. This is a matter that has received much attention from all fruit-growers. The influence of different modes of training and pruning is very great on the bearing qualities of trees. The peculiarities demanded by the various fruit-trees, vines, and bushes, are given under these articles respectively. We give here only some general principles. The health, beauty, and profit, of most fruit-trees depend upon judicious pruning and training. The following are the general objects:-- 1. To secure regular growth and prevent deformities, and thus promote the health of trees.
