object draws in line; then, as the roll brings
the piece right in elevation, it is fired.

[39] Many officers are of the opinion that this order should be
divided--"Load with Cartridge," and "Load with Shell." But those guns
would be very badly served which should wait until this time to give the
order for the species of projectile or class of fuze required. _After_
"Load," is the proper time to give subsidiary order to Shellmen what
projectile and length of fuze to bring for next fire.

[40] "In 10,000 fires, when testing guns of different calibres, with the
regulation locks, less than fifty primers failed from all causes."
