A solitary wasp is apt to select inconvenient places in which to build a mud-cell wherein to deposit its egg, and the store of live caterpillars destined to be the food of its young when hatched. You find a keyhole, or the tap of a filter, filled with mud as the result of this wasp's labours. It works so rapidly that it generally completes its job in the course of a day. An even more inconvenient site for its nest is the sleeve of a garment left hanging on a peg, especially if you put the garment on while the wasp is at work. A small colony of social wasps built their comb under the refectory table of the village Mission-house. They were so determined to remain that for some months they resisted all attempts to get rid of them, returning as often as they were dispersed. Cockroaches, some of great size, abound in most houses, and are very destructive. They nibble the bindings of books, and cut quaint devices, which look almost as if they had been done with a pair of scissors, in clothes put away in drawers. They run at an amazing pace when they think they are in danger. Jet black ants, enormously big and warlike in appearance, come into bungalows, sometimes in unpleasantly large numbers, to see what they can pick up. They are not really aggressive, nor do they do any particular mischief. Another kind of ant, very like an ordinary English one though smaller, is a great trial to housekeepers. They get into the bread and sugar and other stores, and though cupboards are generally set in saucers of water on account of insect depredators, these ants often manage to get in. White ants are most destructive in a house if it is built of materials which they can deal with. In the case of many houses in India, mud is used instead of mortar, and the structure suffers greatly if the white ants take possession. All woodwork, including furniture, ought to be of teak, because they are unable to burrow into it. Sound hard floors are necessary, so that when ants try to work their way upwards they may find their road blocked. Otherwise, in the course of one night, they will eat large holes in a mat or carpet, coming up from beneath. They make havoc in a library if they get amongst the books. Many ant-heaps out in the country are so large as to be conspicuous objects. Scorpions may be found anywhere. In your bedding, in your boots, in your clothes, under your books and, out of doors, chiefly under stones. You soon get into the way of prudently shaking each garment before putting it on. The scorpion averages about two inches in length, but they vary a good deal in size, and also in colour. They much resemble a little lobster in appearance. Their sting is not dangerous under ordinary circumstances, but the pain is great, and resembles a blow on the funny bone, continuing acute for some hours. The boys, sleeping on the floor and having bare feet, get stung now and then, and generally make great lamentations over the misfortune.
