Before applying the silver gray acid stain, the wood should 

 first be sponged with cold water and sand papered when dry. Also 

 sand paper again when the stain is dry, which is not necessary when 

 using an oil stain. Add water to make silver gray acid stain 

 lighter. 



To rub varnish to a dull finish use a piece of rubbing felt 

 about four inches square, dipped alternately in finely pulverized 

 pumice stone and crude oil or pulverized pumice stone and water. 

 For a very dull finish use hair cloth or curled hair, crude oil and Methods of 

 a coarse grade of pumice stone. When oil is used, after the gloss Rubbing 

 is thoroughly removed, the work should be wiped off with clean, Fmishes 

 soft cloths or cotton waste. When water is used, the surface 

 should be washed with water and dried with a chamois skin, then 

 oiled off with linseed or rubbing oil used sparingly on a soft 

 cloth or cotton waste. The water rub method is the only one suit- 

 able for rubbing white enamel. 



For a polished finish carry out the water rub method to the 

 point of oiling off, then rub with rotten stone and oil or rotten 

 stone and water. Where rotten stone and water is used, finally 

 apply a little rotten stone to the palm of the hand, bringing up 

 the high polish by the friction of the hand. After the surface has 

 been polished, oil off in the same manner as described above for 

 the water rub finish. 



Of prime importance is the matter of thorough sanding. Where 

 at all possible, all flat surfaced finish, including round edge case and 

 base should be machine or drum sanded. Hand scraping on the 

 bench is to be discouraged at all times, as the uneven pressure of 

 the scraper scuffs the sap section, leaving the grain slightly raised. 

 The machine, on the other hand, revolving at high speed, takes 

 the surface down uniformly, while at the same time the heat gen- 

 erated by the drum likewise gives a polished surface to the wood 

 itself. When this work is completed at the local planing mill, or 

 wherever it may be done, the stock should be bundled and wrapped B e f ore use 

 in paper before delivery to the job in order to prevent soil, dust 

 and finger marks from reaching it. In other words, it should 

 be handled carefully with proper regard for its worth and use, and 

 not thrown down on the wagon bottom or floor to be trod upon 

 and kicked about until ready to install, as is so often the case. 

 After such careful handling, it should likewise be cleanly installed, 

 after which the painter may proceed at once with his work, having
