A Day's Elephant Hunting in Essex. 31 hoed potatoes. Thus we reach the brink of one of the pits. Here, still accompanied by the ladies of our party, we begin to descend to the realms below. We reach the lower terra firma by a course of wheelbarrow planks. At length we are all assembled, first to receive instructions from our guides, and then to unearth what game we can for our- selves. It now begins to dawn on the minds of the unini- tiated of our party that elephant hunting in Essex, in these modern days, is an underground sport—a recreation restricted to the subterranean world and no longer carried on in the open. We have now descended from the upper air into the ex- cavated bed of some ancient river or lake. It might be misleading, as will hereafter appear, if we said we were standing in the bed of the ancient Thames. And yet these alluvial precincts of the Roding certainly lie within the great shallow trough of what we now call the Thames Valley— that old, incalculably old, line of drainage which has seen so many and eventful changes in the physical geography of south-eastern England. Enough for the present that this excavation is the inlet to the zoological world beneath. But let us be sceptical and take nothing for granted. We are determined to sift to the bottom the strange stories told of these Ilford pits. If we are really standing in an old river-bed, we may demand to see some trace of the various organic remains which a river is always depositing with its sediment. We know that the Thames of to-day is always embedding in its mud some specimens of the aquatic or terrestrial life of the period—the shell-fish that live and die in its waters, and the land animals that are constantly, by accident or design, borne down in the stream. As in some future deserted bed of the Thames, milleniums hence, the fauna of to-day may be disembedded by the Saturday afternoon naturalists of the period, so we, in this Ilford excursion, should expect to discover in the earth around us some relics of the ancient Thames Valley, deposited milleniums ago. This then is what we see as we stand down below in the pit looking up to the daylight. A perpendicular face of the
