where the windows were situated in the room. Though all doors and windows were closely shut, we could feel the dust entering in clouds through the cracks, making it quite unpleasant breathing. When the storm caught us we had to stand and wait, I must own with some fear as to how it was going to end. Up to this time the storm had come up and fallen on us in total silence: now, after about ten minutes of pitch darkness, we could hear in the far distance the wind coming. It came up with cyclonic force, and then everything in the way of tins and buckets began to be blown in every direction, and the horses to gallop about neighing, evidently very much frightened. The wind was the forerunner of the rain, which gradually began to clear the air, though, of course, for some time it rained mud, much to the detriment of the houses, and to anyone unfortunate enough to be caught out of doors in the storm; indeed, one of our friends, who insisted on starting for the station just as the storm descended on us, was found crouching under his umbrella by one of the posts of the railway fence, with a face as black as a sweep's, and, by then, deeply repentant that he had started for the station against advice. Indeed, many caught out in camp by the storm lost their lives through falling into wells, and, in some cases, the river. But, fortunately, nowadays--principally, I fancy, owing to the larger area of country under cultivation--these dust storms do not recur. LOCUSTS. During the past century considerable study has been centred upon the life and habits of the locust, mainly from the desire to seek its subjugation and destruction, and, whilst much general biological information has been written upon the subject, there are things which we do not yet know about this insect or its habits. We do not know what precise influences cause their migration, nor do we know what is the exact length of life of the locust or its breeding power, or the precise locality in any country which may be defined as its permanent abode. Locusts are classified under the order of orthopterous insects of the family Acrydiidae, and are very closely related to grasshoppers. There are a large number of species, the differentiating features being more or less the form and sculpture of protorax, the size of the head, the length and size of the prosternal spine, the comparative length and size of the hind thighs and shanks, the amount and arrangement of the tegmina mottlings, the comparative length of wings, and the general build of the entire insect, which may be robust or fairly slender.
