es immediately following, with
such remarks as he may deem proper to secure better precaution or more
convenient arrangement, with a request that the memorandum, or a copy
of it, may be delivered to the Ordnance Officer at the Yard where the
vessel is refitted or laid up at the end of the cruise.

147. When cartridges are filled for issue to any vessel, the powder
should be selected, as far as practicable, from deliveries made by the
same person, and at the same time or date; and the tanks in which they
are stowed must be marked with white paint on the upper sides, with
the same marks as the barrels from which the powder was taken, giving
the date of manufacture and the maker's name.

148. Great irregularities having been observed in the weights of
cartridges supplied from different stations, it is ordered that at
least ten measures shall be weighed at each filling, and allowance
made for different densities. (See Art. 171.)

149. Whenever powder is returned into the powder-houses from vessels,
and the powder emptied from the cartridges, care must be taken to have
the barrels or other vessels in which the powder may be placed marked
in the same manner and registered in the Magazine Ledger, so that the
maker's name and date of manufacture of all powder may be correctly
known and carefully preserved for reference.

150. The names of vessels from which powder is received, the length of
time which the powder has been on board, and the station on which the
vessel has been employed, should also be noted and reported by the
Ordnance Officer, that reference may be had to the notes in case it
should be desired in subsequent examinations of the powder.

151. In some instances where powder has been condemned by survey, it
has been directed to be thrown overboard. This should never be done;
the nitre contained, which forms three-fourths (3/4) of the powder, is
still perfectly good, and can be made serviceable. In future,
condemned powder is always to be returned to the United States.

152. The Ordnance Officers, when they supply vessels with powder, or
remove any from them, must report to the Bureau by the earliest
opportunity all the information which is required to be noted by
Articles 147, 149, 150, immediately preceding; and when powder is
received from vessels returning from cruises, or after it has been
long embarked, they are to forward to the Ordnance Yard, Washington, a
sample of two pounds and one-fourth, properly l
