gress, it will be found that some ranges, 

 with the least charge, will exceed some 

 of those with the greatest. 8. If two 

 pieces of cannon with the same bore, but 

 of different lengths, are successively fired 

 at the same elevation, with the same 

 charge of powder, then it will frequently 

 happen that some ef the ranges with the 

 shorter piece will exceed some of those 

 with the longer. 9. Whatever operations 



are performed with artillery, the least 

 charges of powder with which they can 

 be effected are always to be preferred. 

 10. No field-piece ought at any time to 

 be loaded with more than one-sixth, or at 

 most one-fifth, of the weight of its bullet 

 in powder, nor should the charge of any 

 battering piece exceed one-third of the 

 weight of its bullet.
