cules beetle (Dynastes Herculis) and the harlequin (Acrocinus longimanus); the former attains a size of five inches in length, and the latter infests the rubber-trees. Another beetle one of the Elaterida (Pyrophorus nyctophorus) - gives a most brilliant and constant light, quite as bright as the cacuyo of the West Indies. All through the highlands wasp-nests of large size and curious form are seen in the trees; ants also build mud-nests in the trees and on posts. Many chapters might be written of the habits of the Central American ants, which are perhaps the most abundant of indigenous insects, -the little crazy ant," which runs rapidly in all directions, seemingly without any object; the zompopos, or leaf-cutters (Ecodoma), whose trains are seen all through the forests, bearing above them the great sail-like fragments of leaf they have cut to stock their homes; the comajen (white ant), which destroys dead-wood and is intolerant of light; the fire-ant; and many others. The zompopos are very destructive in the vegetable garden, and indeed would quickly destroy a cacao, orange, or coffee plantation if allowed to establish their immense burrow in the midst. Some of the burrows are thirty feet in diameter, and can only be destroyed by persistent efforts, — fire, coal-tar, and carbolic acid being the best agents of destruction. The sandflies are almost unendurable along the coast at certain seasons, and so are the mosquitoes (the genuine Culex mosquito, with striped body and black lancet) on the rivers. House-flies are not seen at Livingston; but all through the country the "botlass" is a pest. A bite by this fly leaves a persistent black spot, surrounded by an inflamed circle. Jiggers, beef-worms, and

coloradias are troublesome about the towns and where there is uncleanness. The garrapatos (Ixodes bovis) are often found on horses and other animals, and when full are as large as a coffee-bean. Man does not escape this pest; but they are so large that they are easily picked off, especially if one has a monkey.

Among the mollusks the conch holds an important place both as an article of food and as an instrument of noise. Three kinds are distinguished, the queen, king, and horse; the two last being the best for eating, while the first is much sought for cameo-cutting. A fine pink pearl is found in some of the shells. I consider a conch-soup quite equal to oyster-soup; but it is said (with some reason) to be a strong aphrodisiac. Madrepores, corals, seafans, and the varied inhabitants of reefs, are found in considerable variety, and are now the subject of collection and study by at least two competent observers. Jellyfish (Medusa), Portuguese men-of-war (Physalia), and star-fish (Asterias) are abundant, and a naturalist would have a good harvest on the cayos and reefs of the Bay of Honduras.

dwelling among the more marked phenomena of Nature. It is a mistake to suppose that the eye sees all that is impressed on the retina, that the ear catches more than an insignificant share of the innumerable sounds falling ceaselessly on the tympanum, or that the mind interprets many of the marvels that each instant presents to it. Only the educated eye, the practised ear, the cultivated mind, can appreciate what the Creator has placed before it in this beautiful world whose wonders no human understanding, however taught, is capable of wholly comprehending. The worldly wisdom of the saying that "familiarity breeds contempt " is applicable to the greater portion of humanity; and dwellers among the Alps cease to see, if indeed they ever saw, what strikes the dweller on the plain with awe as he gazes for the first time at the Jungfrau. To a thinking, studying man, familiarity is the mother of awe.

In a region where the molecular forces, those mighty slaves of a Divine Will, are working out of doors, so to speak; where from the summit of a volcanic peak one can count scores of others ranged on his right hand and on his left; where he can see, if he has opened the
