3 thirty feet before the suitable "stone" is reached, the flint is got to the surface without any rope, ladder, basket, or windlas, or, indeed, any mechanical appliance whatever. The modus operandi consists in sinking a series of alternat- ing ledges or steps, in such a manner that, when the bottom is reached, it is some ten or twelve feet away from the perpendicular line below the opening; each of the steps or ledges is from three feet at the top step to six feet at the bottom one, and the excavator jumps or drops down, but climbs up by means of footholes picked in the vertical sides of the steps. The shaft does not go straight down vertically, but follows a zig-zag course in a diagonal direction, proceeding alternately forwards and sideways. The shape of the shaft may be realized by making a model in tin or cardboard. When the vein or layer of good flint is reached, a horizontal tunnel is driven as in an ordinary mine, the worker bringing his lumps of flint to the bottom of the step-like shaft, where he throws them up on to the first ledge; clambering up, he repeats the operation on to the next ledge, and so on, until he gets to the surface, where the excavated flint is stacked in one-horse loads, called "jags." These jags are loosely covered with loppings of fir-trees to protect the flint from the sun and wind, which are said to spoil its character for flaking up well. It is generally supposed that the age of flint implements can be proved by the patinated or semi-glazed appearance of the fractured surface, and to some extent this is so; but it is a curious fact that at Brandon this formation of patina takes place under some conditions very rapidly, and to such an extent that the glaze resembles porcelain, and such examples are known to the natives as china-faced flints, and may often be seen as ornaments in the cottages of the villagers. The loads of excavated flint are brought down to the village as required; there is no regular gun-flint factory, but the work is done in little sheds, often at the back of the cottages. The first operation consists of "quartering" the flint, as it is called—that is, breaking it up into pieces
