Lime duster

1872. The lime-duster (fig. 491.) is made of tinned iron, and is twelve inches long, and seven inches wide at its broadest part. The handle (a) is five inches and a half long, and to the top of it is fitted a cap (b), which is put on when the lime is to be thrown on low trees; but, when high trees are to be operated upon, the cap is to be removed, and a pole, of sufficient length to reach the height required, is inserted into the handle. The time for dusting trees with powdered lime is in the dew of the morning. The caustic quality of the lime will not injure the most delicate, freshly expanded foliage. (Gard. Mag., vol. i. p. 415.)
