Dibber, Or Dibble

This instrument for making holes in which to insert seeds or plants, is usually very simple in its construction, being at the best the head of an old spade-handle. To secure uniformity of depth in planting beans, etc, by this instrument, it is useful to have it perforated with holes to receive an iron peg, at two and three inches from the point, as in the following outline. Fig. 34. It should be shod with iron; for if this be kept bright it will make holes into which the soil will not crumble from the sides. The crumbling is induced by the soil's adhesion to the dibble. For planting potatoes, a dibble with a head three inches diameter at the point, six inches long up to the foot-rest, and with a handle four feet long, is to be preferred. For the insertion of seed a dibble that delivers the seed has been invented by a Mr. Smith.
