To Remove Iron Rust - Purchase ten cents' worth of oxalic acid; put in a pint bottle; fill with soft water and set away, ready for use. Do not use until ready to put garment into suds for washing, as it will eat the fabric. Hold garment in the sun and wet thoroughly. It will quickly disappear.

Baking Powder - For 1 even tablespoon of best baking soda use 3 even tablespoons cream tartar, and for every teacup of the mixture use 1 even teaspoon of corn starch.. Sift through a sieve several times and put in a tight can.

Baking Powder -- Ten ounces cream tartar, 5 ounces bicarbonate soda, 1 level tumbler corn starch. Mix thoroughly, usually sifting several times. This makes one quart of good, pure baking power.

Salve Receipt -- One pound resin, 1 ounce balsam fir, 2 ounces bees' wax. 1/2 ounce linseed oil, 1 ounce Burgundy pitch, 1/2 ounce mutton tallow.
