DETONATING SYSTEM. 



caps of bad quality has perhaps doubled the number of 

 accidents- For instance, French caps, being now to be 

 had for about two francs a thousand, are frequently 

 imported to England, and sold at an immense profit ; 

 and, although these may do very well with weak French 

 powder, yet they are so unfit to be trusted with our 

 powder, that the loss of many sportsmen's eyes has 

 been the consequence. I know one gunmaker who re- 

 commended them for no other purpose than to ruin 

 the copper-cap guns, and thereby improve trade. 



N. B. If the hole of your nipple should become 

 choked up with copper, as is frequently the case, put 

 on another cap and let it off, before you load the gun; 

 and nine times out of ten the force of the fulminating 

 powder will clear the hole. But if this is done, it 

 should be with w//-corrosive caps ; as the other pre- 

 paration, unless mixed with powder y materially injures 

 the iron. This being so quick a remedy, we may 

 always try it before we have recourse to the nipple- 

 wrench. Let us now inspect the breechings before we 

 go on to copper primers.

The two dotted lines point out the hole into which the gas from 

 the cap is driven.
