This little town of Pachuca has long been a place of some importance in the world, as regards mining-operations. The Aztecs worked silver-mines here, as well as at Tasco, long before the Spaniards came, and they knew how to smelt the ore.
Possibly the present diggings have struck only a large branch or a break. Here mining-operations have been extensive, and about 1,800 tons of rich stuff have already been brought to bank. The diggings begin with an open cut of 110 feet; this leads to a tunnel in the rock partly timbered, by which the lode with a dip of 41º is bisected.
The Ammophila does not as a rule trouble about her burrow, or at least does not complete it, until she has caught her caterpillar. During the mining-operations, the game is laid somewhere high up, out of reach of the Ants, on some tuft of grass, or the twigs of a shrub, whither the huntress, from time to time, stopping her well-sinking, hastens to see if her quarry is still there.
