Fours may be counted at the halt or marching, mounted or dismounted, in line or in column of twos or troopers. In counting fours in column of twos or troopers the elements count off successively from front to rear in the column and from right to left in each two. =Eyes right= is not executed when counting fours from column of twos or troopers. TO TAKE INTERVALS AND DISTANCES. =85.= Being in line at a halt: 1. =Take intervals, to the right (left)=, 2. =MARCH=, 3. =Squad=, 4. =HALT.= At the command =march=, all face to the right and the leading trooper steps off; the other men step off in succession, each following the preceding trooper at four paces. At the command =halt=, given when all have their intervals, all halt and face to the front. =86.= Being at intervals, to assemble the squad: 1. =Assemble to the right (left)=, 2. =MARCH.= The trooper on the right stands fast. The other troopers face to the right, close by the shortest line and face to the front. =87.= Being in line at a halt and fours having been counted: 1. =Take distance=, 2. =MARCH=, 3. =Squad=, 4. =HALT.= At the command =march=, No. 1 moves straight to the front; Nos. 2, 3, and 4 in the order named, move straight to the front, each stepping off so as to follow the preceding man at 4 paces. The command halt is given when all have their distances. If there be more than one No. 1, all the Nos. 1 move forward together, guiding on the right trooper. The same principle applies to the other numbers. =88.= The normal interval and distance of 4 paces indicated, respectively, in pars. 34 and 36, may be increased or diminished by adding to the corresponding preparatory command the indication of the interval or distance desired; thus: 1. =Take interval to the right at 1 pace=, 2. =MARCH=, etc.; 1. =Take distance, at 2 paces=, 2. =MARCH=, etc. =89.= Being at distances, to assemble the squad: 1. =Assemble=, 2. =MARCH.= No. 1 of the front rank stands fast; the other numbers move forward to their proper places in line. INDIVIDUAL INSTRUCTION WITH ARMS. MANUAL OF THE RIFLE. =90.= When the recruit has made fair progress in the instruction without arms, including that required by par. 53, he is taught the manual of arms. Instruction without arms and that with arms alternate. =91.= The following rules govern the carrying of the rifle: =First.= The rifle is not carried with cartridges in either the chamber or the magazine except when specifically ordered. When so loaded, or supposed to be loaded, it is habitually carried locked; that is, with the =safety lock= turned to the "safe." At all other times it is carried unlocked, with the trigger pulled. =Second.= Whenever troops are formed under arms, rifles are immediately inspected at the commands: 1. =Inspection=, 2. =ARMS=; 3. =Order (right shoulder, port)=, 4. =ARMS.= A. similar inspection is made immediately before dismissal. If cartridges are found in the chamber or magazine they are removed and placed in the belt.
