"The Tortricina include a great number of small moths exceedingly injurious to orchard and other trees. They are known as "leaf-rollers" from the habit which most of their larva have of rolling up the leaves on which they feed, and thus forming a shelter for themselves. The Green Tortrix occurs in the larva state on the oak, to which it often does great injurt by stripping the trees of their leaves in the month of June. Throughout Southern Europe the vine is liable to the ravages of another species, Aenectra pillariana, while few of our fruit trees are exempt from the occasional attacks of some species or other of the Carpocapsidae, the fruit-eating family of this group." — Encyclopedia Britanica; 1893

"These congregate together under stones, and when disturbed discharge a caustic fluid of an extremely penetrating odor, and so volatile that no sooner does it come in contact with the atmosphere than it passes into a vapour, accompanied by a considerable explosion, during which they seek to escape. When placed on the tongue this guid causes a sharp pain and leaves a yellow spot somewhat similar to that produced by a drop of nitric acid. The Bombardiers are said to be capable of giving off as many as 18 of such discharges at a time." — Encyclopedia Britanica, 1893.

"Many plans may be propagated by planting their leaves or portions of their leaves as cuttings, as, for example, the herbaceous Gloxinia (a) and Gesnera, the succulent Sempervivum, Echeveria, Pachyphytum, and their allies and such hard-leaved plants as Theophrasta (b). The leaves are best taken off with the base whole, and should be planted in well-drained sandy soil; in due time they form roots, and ultimately from some latent bud a little shoot which forms the young plant. The treatment is precisely like that of branch cuttings. Gloxinias, begonias, etc., grow readily from fragments of the leaves cut clean through the thick veins and ribs, and planted edgewise like cuttings. This class of subjects may also be fixed flat on the surface of the cutting pot, by means of little pegs or hooks, the main ribs being cut across at intervals, and from these points roots, and eventually young tubers, will be produced." — Encyclopedia Britannica, 1893
