“Five of the volumes were bound in cloth. On these the principal damage appeared at the edges, which were eaten away and disfigured by large burrows extending inward. Two volumes were bound in leather. The edges of these were not so much disturbed; but numerous perforations, somewhat like shot-holes externally, passed through the leather, enlarging and ramifying in the interior. As if made by smaller insects, the sides of these holes were neater and cleaner cuttings than those in the burrows on the edges of the other volumes.

“The insects were all identified as well known enemies of libraries, cabinets, and wardrobes. One of them is a species of what are commonly designated ‘fish bugs,’ ‘silver fish,’ ‘bristle tails,’ &c. By entomologists they are called Lepisma; the species in hand is probably Lepisma saccharina. It is a small, elongate, silvery, very active creature, frequently discovered under objects, or between the leaves of books, whence it escapes by its extraordinary quickness of movement. Paste and the sizing or enamel of some kinds of paper are very attractive to it. In some cases it eats off the entire surface of the sheet, including the ink, without making perforations; in others the leaves are completely destroyed. The last specimen of this insect in these books was killed February 5, 1893, which proves the species to be sufficiently at home in this latitude.

“The second of the three is one of the ‘Buffalo Bugs.’ or ‘Carpet Bugs,’ so called; not really bugs, but beetles. The species before us is the Anthrenus varius of scientists, very common in Boston and Cambridge, as in other portions of the temperate regions and the tropics. Very likely the ‘shot-holes’ in the leather-bound volumes are of its making, though it may have been aided in the deeper and larger chambers by one or both of the others. The damage done by this insect in the house, museum, and library is too well known to call for further comment. Living individuals were taken from the books nearly a year after they were isolated.

“The third species had disappeared before the arrival of the books, leaving only its burrows, excrement, and empty egg-cases, which, however, leave no doubt of the identity of the animal with one of the cockroaches, possibly the species Blatta Australasiæ. The cases agree in size with those of Blatta Americana, but have thirteen impressions on each side, as if the number of eggs were twenty-six. The ravages of the cockroaches are greatest in the tropics, but some of the species range through the temperate zones and even northward. An extract from Westwood and Drury will serve to indicate the character of their work:—

“‘They devour all kinds of victuals, dressed and undressed, and damage all sorts of clothing, leather, books, paper, &c., which, if they do not destroy, at least they soil, as they frequently deposit a drop of their excrement where they settle. They swarm by myriads in old houses, making every part filthy beyond description. They have also the power of making a noise like a sharp knocking with the knuckle upon the wainscotting, Blatta gigantea being thence known to the West Indies by the name of drummer; and this they keep up, replying to each other, throughout the night. Moreover, they attack sleeping persons, and will even eat the extremities of the dead.’

“This quotation makes it appear that authors as well as books are endangered by this outlaw. With energies exclusively turned against properly selected examples of both, what a world of good it might do mankind! The discrimination lacking, the insect must be treated as a common enemy. As a bane for ‘silver fish’ and cockroaches, pyrethrum insect powder is said to be effectual. For a number of years I have used, on lepisma and roach, a mixture containing phosphorus, ‘The Infallible Water Bug and Roach Exterminator,’ made by Barnard & Co., 7 Temple Place, Boston, and, without other interest in advertising the compound, have found it entirely satisfactory in its effects. Bisulphide carbon, evaporated in closed boxes or cases containing the infested articles, is used to do away with the ‘Buffalo Bugs.’—Very respectfully yours,

“Samuel Garman.”

I can remember that many years ago there was to be seen in the bookshop of John Penington, Philadelphia, a book-worm preserved in spirits in a vial. The manner in which this species of teredo penetrates wood and leather as well as paper is not the least curious of its habits.

The great amount of injury inflicted by boring-insects in books, wood, and all weak substances is sufficient reason for giving so much space to this subject. From a ship to a manuscript, nothing is safe from them.
