But all this promotion is yet a long way off. One morning, while Scius is still a private, he hears, not the "taratantara" of the long straight trumpet which calls to ordinary work, but the sound of the military horn, which means that the legion is to march. He helps to pack up the tent, the hand-mills, and other indispensable needments, and to place them on the mules, packhorses, or waggons. He then puts on his full armour, although, if it is hot, and if there is no immediate danger, he may sling his helmet over his shoulder, while his shield, marked with his name and company, may perhaps be stacked with others in a baggage-waggon. His food-supply for sixteen days--the Roman fortnight--is wrapped in a parcel, and this, together with his eating and drinking vessels and any other articles such as would appertain to a modern knapsack, is carried over his shoulder on a forked stick. It is known that to-night the army will be obliged to camp on the way, and it is a binding rule of the service that no camp arrangements shall be left to chance. Surveyors will ride on ahead with a body of cavalry, and will choose a suitable position easily defended and with water near. They will then outline the boundaries according to a certain scale, and will parcel out the interior, according to an almost invariable system, into blocks or sections to accommodate certain units. When the legion arrives, it marches in with a perfect understanding as to where each company of men and each part of the baggage-train is to quarter itself. Being in an enemy's country it is not enough simply to post sentries. A trench must be dug and a palisade erected round the camp, and for that purpose every soldier on the march has carried a couple of sharpened stakes and a sort of small pickaxe. It may therefore be readily understood that Scius is heavily laden. Besides the weight of his body-armour and his shield, pike, and sword, his orthodox burden is about forty-five English pounds.
