* Shell for coast service. 
Note. —The cartridges and the projectiles will be the same at those actually in use by the naval 
service, with the exception of the projectile for the howitzer of 8-66 in., which will be specially 
prepared for the proof of this gun. 
Two hay-wads will be used in each round for all guns; one on the powder, the other on the 
last projectile, with the exception of mortars, which are fired without wads, and also rifled guns, which 
require but one, on the powder. 
The hay-wads will be rammed home with two blows. 
The hay-wad will be one-thirtieth of the weight of the spherical solid shot, and will be in length 
and thickness the diameter of the shot.
