422 ENGRAVING* 



grees ; and that you may do it ^vith greater exact- 

 ness, take care that your strokes be not too close 

 nor too wide. 



In the course of your v/ork scrape off the 

 roughness which arises, with your scraper; but 

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

 and 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, and show what you have done to the best 

 advantage. 



Any mistakes or scratches in the plate may be 

 rubbed out with the burnisher, and tlie part levelled 

 with the scraper, polishing 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 to 

 finish the piece you had etched, by graving up the 

 several parts to the colour required ; beginning, as 

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

 ing gradually with the stronger, till the v/hole is 

 completed. 



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 too great a 

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

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

 sloping at a convenient distance between your 

 work and the lights will preserve the sight ; and 

 when the sun shines, it cannot possibly be dis- 

 pensed with.
