To make Baking-powder.—Mix together ten ounces of bicarbonate of soda, eight ounces of tartaric acid, and a pound of corn-flour, ground-rice, or wheat-flour. Thoroughly mix the powders, pass through a sieve, and store.

It is essential that the several materials used in the preparation of baking-powder shall be separately fire-dried with thoroughness previously to being mixed. The presence of the smallest quantity of dampness renders the mixture quite inoperative. Baking-powder should therefore be carefully stored in air-tight boxes or bins.

To keep Cut Flowers fresh, they should be supplied with fresh water every morning, when also a tiny bit of the end of the stem should be cut off and the whole stem gently wiped with a cloth. No leaves should be left on that part of the stem which is under water.
