(6) J. M. D. asks: Is there any virtue in the “divining rod,” so called, as a means of determining the locality of hidden streams of water? A. None whatever. The bobbing of the stick is due to a muscular pressure by the holder.
(7) C. W. C. desires (1) a recipe for a stain to imitate mahogany on white birch wood, that will not raise the grain of the wood. A. A dark mahogany stain is made as follows: Boil half a pound of madder and 2 ounces of logwood chips in 1 gallon of water, and brush well over the wood while hot; when dry, go over the whole with pearlash solution, 2 drachms to the quart. 2. Can you give recipe for making the acid stain? A. In the acid stain you take nitric acid, and dilute with 10 parts of water, and wash the wood with it. 3. Are there any books which give full directions for imitating the different woods? A. We would recommend for your purpose Spons’ Workshop Receipts (second series), which we can send you, postpaid, for $2.00.
(8) A subscriber asks how to make spirit varnish suitable for varnishing carved wood. A. Take 1 ounce copal and ½ ounce shellac; powder them well, and put them into a bottle or jar containing 1 quart alcohol. Place the mixture in a warm place and shake it occasionally until the gums are completely dissolved; and when strained the varnish will be ready for use.
