“It is an essential part of training for war that the men are taught to care for themselves, so as to maintain their physical fitness. To this end the necessity for taking the most scrupulous care of their clothing, equipment and accoutrements will be explained to them.” The following is the syllabus (slightly condensed) of a Maintenance Course for Tank Commanders: How to drive a Tank. How to set a magneto. When an engine is misfiring or overheating. When an engine is knocking too badly to continue working or is not pulling. When carburation is bad. When a Tank is at such an angle that it is dangerous to run the engine. The causes of engine failures and how to correct them. How the autovac works. The correct tension for fan belts. When an engine bed is loose. How much petrol, oil, grease, and water should be used during average hour’s run. When road chain sprocket wheels or pinions should be changed. How long it takes to change a set of sprocket wheels and pinions. When a track or the Coventry driving chains are too slack. When a clutch is too fierce, and how to correct it. When a clutch is slipping, and how to adjust it. When secondary gears are too much worn for further service, and what is the effect of their not being fully in mesh. How long it takes to change such gears. When tracks or secondary gears are over or under lubricated. When brakes are operative or not. How long it takes to prepare a Tank for a day’s run. How long it takes thoroughly to clean and adjust a Tank after a day’s work. How long it takes to detrain Tanks and adjust sponsons. How the equipment of a Tank should be stowed. The appliances which are necessary to dismantle various sections of a Tank, and how it should be done. That it is just as necessary for a Company Commander to inspect Tanks daily as it is for a Cavalry Squadron Commander to inspect his horses. For an interesting “Immediate Action Course,” _i.e._, first aid to the engine, the following directions are given to instructors: “In order to inspire confidence at the outset, particular stress should be laid upon the fact that in a Tank there are practically only three causes of engine failure--Valves--Ignition--Petrol. “If this is borne in mind, a very little experience in the simple operations connected with these three functions, coupled with a little training in diagnosis, will enable students to deal very easily with troubles as they occur. “Drivers should know by the ‘feel’ of their engine whether it is firing correctly or not, and any member of a crew ought to be able to detect and report at once any irregularity in the sound of an exhaust from outside the machine. “When the students have been through a course (using the book) of what to do when: “1. The Engine won’t start, “2. Engine starts and stops after a few Revs,
