 have known some to be in use full six years without losing their 

 covering. Small silver chains, such as those sold at eight shillings, 

 should have 12 grains ; pencil-cases, of ordinary size, should have 

 from 3 to 5 grains ; a thimble from 1 to 2 grains. These suggestions 

 will serve as a guide to amateur gilders, many of whom, having 

 imparted only a colour to their pencil-cases, feel chagrin and disap- 

 pointment upon seeing them speedily become bare : hence arises 

 much of the obloquy thrown upon the process.
