ECONOMISING IN COAL

HINTS BY AN EXPERT.

During these times of war when householders are obliged to take half their coal in Hie shape of slack, the following hints irniv be useful to consumers, states Mr. Bingham, Karori Borough Engineer: Coal slack or dust is to tfi found in nearly every housenold. .It is generally used to Ixin'k a fire, burns dull, liuich ot it drops through the grate, and, it Ki so unsatisfactory that one often pays to have it removed. Buy a small quantity of cement, then add ono part, by inoaMire (not wei?hlj to twenty jwrls ot coal slack, mix very, thoroughly in a dry slate, then add gently and by degrees, a small quantity, of water, again well mixing all iho time. Care must lie taken not to make the combination too wet; it should just hold together when squeezed in the hand. It is now readv to place ill a mould. An excellent' one is an ordinary small flowerpot four in five inches in diameter. Press mixture into this firmly, and it can be af once turned out hy inverting pet. Keep in a drv, cool place for about our davs, and it is ready to burn, which it will do like an ordinary lump of con . Alternatively the mixture can lie moulded in the hands, like a snoivhall, and in a dai r or two bccomos quito firm. N.8.--AS a guido to correct proportion n ljudcot measure (say. 3 <rfllions) of co<al dust will require 11-5 pint of cement (i e the 5-ilich flower-not about tlireeimrt« full), (inil albont 21 pints of waiur. Uniform mixture is the secret of success and a batch as above will be found a convenient quantity to work up at a time.
