СКАЧАТЬ bad reputation. I know of no modern parallel. In Shakespeare's time a similar popular prejudice was entertained against one of the most useful servants that farmers and horticulturists possess. The well-known lines —

      "The toad, ugly and venomous,

      Holds yet a precious jewel in its head" —

      were but the echo of this crude and cruel fancy. So with our Thelyphonus. It is not only absolutely harmless, but, as I shall soon show, one of the most useful helps in keeping within bounds one of our most serious pests.

      The comment that I once heard, by a not over-intelligent and somewhat profane individual, upon seeing a dead whip scorpion – "Any – fool can see that that critter is rank pisin!" – probably partially explains the matter. It must be conceded that the looks of the Thelyphonus are decidedly against it. Its long, frisky tail, its big, threatening claws, and its generally uncanny and vicious appearance are quite sufficient to inspire caution if not positive dread. It "looks pisin," and that settles it with the ignorant. With the better informed the fact that the creature belongs to a bad family, that its nearest relatives are unquestionably venomous, may help to explain, though it can hardly excuse, the widespread currency which even scientific men have helped to give to a most erroneous and slanderous belief.

      And now as to the food question. This, of course, was a very vital matter to my little prisoner, and one of great interest to me. After the failure of the cockroach diet, I next tried grasshoppers. These also have been declared to be greatly relished by the Thelyphonus. I did not find it so. The first one placed in the cage was, to be sure, partially eaten. But, unfortunately, a colony of ants had got into the cage, and were dining on my dead Gryllus. This left the matter a little uncertain. On fencing out these intruders, and repeating the experiment with the same and half a dozen other species, I became convinced that my Thelyphonus, at least, was not fond of grasshoppers. Then began a kind of general system, or no system, of haphazard feeding, or rather trials of food. My marketing range for my particular "boarder" was by no means a limited one. During the month of September, when most of these investigations were in progress, Florida is by no means deficient in insect life. Every day from two to ten new and different species were placed in the cage. A list was kept, to avoid repetition, until my captive was offered her choice of something over a hundred varieties of "bugs," worms, grubs, spiders, ants and their eggs, lizards, butterflies, etc. – everything, indeed, that I could think of or conveniently catch, which it seemed possible my little captive might fancy. Of all this heterogeneous collection, nothing, so far as I could see, was ever killed or eaten. A tiny piece of fresh beef, placed in her cage at night, was the only thing that I could persuade her to touch. Even of this I am not absolutely certain. In the morning these little pellets of fresh meat were usually found rolled in the sand and often apparently diminished in size. Several times they disappeared altogether. The presence, however, of other predatory insects sometimes left the matter a little in doubt. But, as my captive remained in good health for over a month while this plan of trial dieting was in progress, I am inclined to think that more or less of the fresh beef was really consumed by her. Still, she took the greatest care that I should never catch her eating, even when surprised with a sudden light at night, a time when she was always especially active.

      I was getting a little tired of this seemingly fruitless investigation, and had about concluded to persuade my Thelyphonus to crawl into a bottle in company with a few drops of chloroform, to have her picture taken, and then forward the "embalmed remains" to the Museum of Natural History in Central Park, New York, to which they had already been promised.

      I concluded, however, to make one more effort. So the next day I spent some time in hunting for new and untried insects, of which I procured half a dozen or so, and among other things quite a lot of so-called "wood-lice," "white ants," termites, our only representative of a family that in most warm countries is so destructive to exposed wooden structures. All of these "finds" were tumbled, as usual, upon the floor of my captive's cage, and I left them with very little expectation that she would see among them anything that suited her fastidious taste. The next morning, to my surprise, every white ant had disappeared; nothing else was touched. The question was solved. For about three weeks my Thelyphonus was supplied each day with a liberal allowance of what in this latitude, at least, seems to be its exclusive food.

      Now, this white ant (Termes flavipes) is in Florida one of our worst pests. Possibly there may be some compensating benefits which they confer, in the more rapid removal of decaying vegetable matter. In most respects, however, they are an unmitigated nuisance. The annual destruction of property, of fencing, building foundations, and exposed woodwork of every kind must be estimated at hundreds of thousands of dollars. The worst of it is, too, that it is impossible to know when they are at work. They are always hidden. In case they are compelled in their destructive labors to pass over the outside of anything, they always build a hard gallery of cemented sand or clay, under which they travel securely. Unfortunately, too, they do not always confine their ravages to dead wood. Every orange grower fears them, and if they once get a foothold the tree that they attack is often destroyed before anything is suspected to be the matter. They "love darkness rather than light," and "their deeds are evil." And it is these miserable pests that my little-appreciated and much-slandered Thelyphonus has been all her life fighting! And those big, strong claws of hers, that look so formidable, what are they for but to tear down and break in pieces the hard, honeycombed structures in which her food is hidden? It was all plain enough now!

These figures represent the expenditures before the war with Spain. That deplorable event will increase them considerably.
