= r HERE is fcarcely any part of the extenfive and important fcience of agriculture that has received greater improvements within thefe few years, than that which relates

to the conftruction of the implements which are neceflary to be employed. Since a

tafte for the art has fortunately been diffufed through the country, and men of great Knowledge and fortune have been induced to engage in it, perfons of ingenuity and mechanical talents have been brought forward and fufficiently encouraged to exert themfelves either in the improvement of the better kinds of the old inftruments, or in the invention of new ones, by which means more convenient and ufeful inftruments and machines have been provided for almoft all the various operations and proceffes that are continually to be performed in cultivating land, and managing the different kinds of bufinefs neceflarily conneéted with it. Among the variety of different im- plements which have been thus prefented to the attention of the agriculturift, fome, as may eafily be conceived, have appeared, that are evidently much too expenfive and complicated in their conftruétion for the purpofes which they are intended to ferve, and others, probably from a want of practical information in the inventors, have not been properly adapted to the ufes for which they were defigned; but in ge- neral they have been fuch as have contributed much to the prefent very improved {tate of the art. 7

The backwardnefs that maybe obferved, and which is fomuchcomplained of in fome particular diftri€is in refpet to the ftate of their cultivation, would feem to depend, in fome meafure, on an attachment to fuch implements as they have been in the habit
