parts, put in a basin, pour over it about 1 pint vinegar, and let it

 saucepan, stand on a gentle fire, stir till perfectly dissolved — see it 

 does not burn at bottom, and not reach boiling point, about 180 

 degrees Fahr. Next add the gum, heat again, and add isinglass. 

 Apply with a sponge.

Leather Dressing. — A fine, brilliant, elastic dressing for leather 

 can be made as follows: — To 31bs. of boiling water, add, with 

 continual stirring, i^lb. white wax, loz. transparent glue, 2oz. gum 

 Senegal, l^^oz. white soap, and 2oz. brown candy. Finally add 

 2i^oz. alcohol, and after the whole is cooled, 3oz. fine Frankfort 

 black. The dressing is thinly applied to the leather with a soft 

 brush ; and, after it is dried, it is rubbed with a piece of fine pumice, 

 and polished with a stiff brush.

 parts, oil of lavender 1 part, essence of citronelle 1 part, spirits 

 of ammonia 2 parts. Method of preparation: — Mix all together,

P.A.TENT Leather Polish. — The following recipe is given by ix 

 German journal as being a good patent leather polish : — Take 60 

 parts whale soap and 500 parts water. Let this soak over-night. 

 Also 60 parts glue, 500 parts water. Let this soak over-night. 

 Boil these each separately, adding the first to the second. When 

 thoroughly boiled add 15 parts wax, 10 parts lamp black, and boil

The Cleansing of Machine Bands. — To cleanse a machine 

 band, it should first be scrubbed with a brush and warm water anrl 

 soap, and then, while it is still wet, a solution of ammonia should 

 be rubbed in, which will saponify the grease in the band. 

 Immediatelv after this, the band must be well rinsed in tepid water, 

 and then stretched out to drv. Before, however, it is quite drv, 

 smear the inner surface — and slightly also the outer surface — with 

 the following preserving solution, viz. : 1 kilogramme of india- 

 rubber heated to 50 degrees, mixed with the same quantity of 

 rectified oil of tur[)entine. When this is completely dissolved, 780 

 grammes of colophonium is added, and after that 750 grammes of 

 yellow wax. When this is well mixed, 3 kilogrammes of train oil, 

 to which 1^^ kilogrammes of melted tallow has been adde^l, are 

 poured in, stirring briskly all the while. When the band is in 

 use its inner surface only shouUi be smeared, the outer- surface not 

 being done after the first time. By this mi^Piis, the tannin squeezed 

 out of the band is rej)laced, slipping is pjevented, and the band 

 remains elastic. One kilogramme equals 21bs. S^ozs. ; loz. equals 

 28 grammes.
