(4) Name of the foundry. 
(5) The date. 
Art. 58. The officers of artillery and government foreman will watch 
these operations, and assure themselves, by frequent verifications during 
the process of boring, that the borers have no irregular motion, shewing that 
their working is deranged. 
Art. 59. The government foreman will keep a note-book for the purpose 
of recording the result of the examinations prescribed by Articles 54 and 56, 
as of any others to which the piece is subjected. 
Section YI .—Examination, ordinary proof, and passing of smooth-bore 
guns . 
Art. 60. The guns being finished, they will, before being proved, be 
subjected to a general examination, made in conformity with special instruc¬ 
tions given to that effect by the minister. The object of this examination is 
to record in positive terms all the defects of dimensions, or others which the 
piece may have. 
Art. 61. The guns which, in the examination directed in the preceding 
Article, have not shewn defects exceeding toleration, will be submitted to 
the ordinary proof, following as much as possible the order in which they 
were cast. 
In this proof the guns will be placed on the sledge-carriages in use, and 
they will be pointed at the angle nearest to 3°, but always in such a manner 
that the shot may surely strike the butt. 
Art. 62. A warning signal gun will be fired before commencing the 
proofs; and during their course a red flag will remain flying on an elevated 
spot, so as to be easily seen by the neighbourhood. 
The guns will be fired with a slow-match, which will permit the gunners 
to be under cover, in case of a gun bursting. In short, no precaution 
against accident is to be neglected. 
Art. 63. The powder, cartridge-bags, and spherical projectiles used in 
the proofs, must fulfil the conditions required by the naval service. The 
cartridge-bags will be made on the mandril which is the regulated one for 
the naval service at the time. 
The wads will be of hay, and will weigh one-thirtieth of the weight of 
the spherical shot; they will be one calibre in length and diameter. 
The powder will be weighed and put into cartridge-bags in presence of 
one of the officers of the commission and the government foreman. 
Art. 64. The ordinary proof for all guns (with the exception of mortars) 
will consist in two shots fired consecutively with the largest charge of 
powder used in the naval service, in conformity with the schedule annexed 
to the present decree. 
Art. 65. For guns, howitzers of 30, and carronades, the charge will 
consist and will be fired as follows:—The indicated charge of powder, a 
wad of hay, two shot and a second wad of hay—ram down twice on each 
wad. For howitzers the charge of powder indicated, a wad, a spherical solid 
shot of the calibre of the shell, and a second wad on the projectile.
