1714. The thrust-hoe (figs. 323. and 324.) consists of a plate of iron attached somewhat obliquely to the end of a handle, either by a bow (fig. 323.), or a straight piece (fig. 324.). These hoes, which are sometimes called Dutch hoes, are used only for killing weeds, or loosening ground which is to be afterwards raked. The thrust-hoe is, consequently, much less useful than the draw-hoe; and it requires more care and skill in its management; as, unless great care is taken, the growing crops will be in great danger or being injured by it. Also, as a man can draw more than he can push, most heavy work will be easiest done by the draw-hoc. Several improvements have been recently made in the hoe, by varying the form of the blade, as in figs. 346, and 347., or by making it sharp on all its edges, as in fig. 349. This last form is the invention of the late Mr. Booker, of Cronstadt. Fig. 348. shows a double Dutch hoe, which is very useful for hoeing between drill crops when they are young.
