1873. A pair of dusting bellows, for scattering powdered lime, powdered tobacco leaves, or any other powder over plants (fig. 492.), is described in vol. iii. of the Gardener's Magazine. This utensil consists of a pair of common bellows, having, instead of the lower board and valve, a piece of tinned iron (a), in the flat end of which (b) are two small valves, one fourth of an inch in diameter, with an opening between them for the introduction of the dust, to which a cap is afterwards screwed on.
