We lay like lizards in the long grass round the stones of the foremost cairn upon the hilltop, and saw the garrison parade. Three hundred and ninety-nine infantry, little toy men, ran about when the bugle sounded, and formed up in stiff lines below the black building till there was more bugling: then they scattered, and after a few minutes the smoke of cooking fires went up. A herd of sheep and goats in charge of a little ragged boy issued out towards us. Before he reached the foot of the hills there came a loud whistling down the valley from the north, and a tiny, picture-book train rolled slowly into view across the hollow sounding bridge and halted just outside the station, panting out white puffs of steam.
