| Once a leash of thin black whips, like the arms of an octopus, flashed across the sunset and was immediately with- drawn, and afterwards a thin rod rose up, joint by joint, bearing at its apex a circular disk that spun with a wobbling motion. Everybody knows that the great reversed triangle of land, with its base in the north and its apex in the south, which is called India, embraces fourteen hundred thousand square miles, upon which is spread unequally a population of one hundred and eighty millions of souls. A military organization may be quite correctly compared to a cone, of which the base with the largest diameter consists of the rank and file; the next higher and smaller section of the cone consists of the next higher grades of the army, and so on to the apex, the point of which will represent the commander in chief. |
