Nos. 5 and 6 operate another trolley and pulley.
Nos. 7 and 8 uncase cartridges.
Nos. 9, 10, 11, and 12 place sections on receiving-table in proper order. If electrical power fails, Nos. 1 and 2 operate hoist by hand-cranks.
Note.—Since the drills for the 10-inch and 8-inch disappearing guns differ from the drill for the 12-inch in so few minor details, no separate questions and answers in these cases are given. In the 10-inch piece the following differences were noted: Nos. 13 and 14 are omitted in the rammer detail; No. 4 in procuring implements attends to the rammer alone; in loading, No. 2 pushes the second section of cartridge into the chamber instead of the fourth; in ramming, the positions from front to rear are Nos. 1 and 9 on right, Nos. 2, 4, and 10 on left, facing rammer, etc. When hoist is on right side No. 10 assists No. 4 (No. 13 being left out).
In the 8-inch piece the rammer detail consists of No. 4 (13 and 14 omitted), the truck detail of No. 11 (12 omitted), and the hoist detail of Nos. 16 and 17 (No. 18 omitted). The duties of the numbers omitted in these details are performed by the remaining numbers in that detail, otherwise the drill is precisely the same as for the 12-inch piece. In extracting a dummy Nos. 2 and 3 do not assist in withdrawing; Nos. 1 and 4 do this.
