greeS ; and that you may do it with greater exact- 

 ness, take care that your strokes be not tbo close 

 no'r too wide. 



In the course of your work scrape off the 

 roughness which arises, with your scraper; but 

 be careful, in doing this, not to scratch the plate ; 

 arid that you may see your work properly as you 

 go on, rub it with the oil-rubber, and wipe the 

 plate clean, which will take off the glare of the 

 copper, arid show what you haVe done to the best 

 advantage. 



Any mistakes of scratches in the plate may be 

 rubbed out with the burnisher, and the part levelled 

 with the Draper, polishirig it again afterwards 

 lightly with the burnisher, or charcoal. 



Having thus attained the use of the graver, ac- 

 cording to the foregoing rules, you will be able td 

 finish the piece you had etched, by gravirjg up the 

 several jiarts to the" colour required ; beginning, as 

 in the etching, with the fainter parts, and advanc- 

 ing gradually with the stronger, till the whole is 

 coiripleted. 



The dry point or needle (so called because not 

 used till the ground is taken off the plate) is prin- 

 cipally employed in the extremely light parts of 

 water, sky, drapery, architecture, &c. 



To prevent any obstruction from 1 too great a 

 degree of light, the use of a sash, made of trans- 

 parent, or fan paper, pasted on a frarrie, and placed 

 sldpirig at a convenient distance between your 

 work and the light, will preserve the sight ; and 

 when the sun shines, it cannot possibly be dis- 

 pensed with.
