“There are in Scripture ten names for locusts. The species mentioned here is called Arbah, which imports multiplicity; a very just name, indeed: for their prodigious numbers almost defy calculation; and the famous Dutch naturalist Leuwenhoek asserts, that every female lays upwards of eighty eggs. When a cloud of these insects alights upon the ground, the devastation they create is dreadful. Adanson, in his voyage to the western coast of Africa, says, that they devoured to the very root and bark; and that there was something corrosive in their bite, which prevented the trees from recovering their power of vegetation for some time. They even attacked the dry reeds with which the huts were thatched. Another traveller tells us that in Cyprus, as he went from Larnica to a garden at about four miles’ distance, the locusts lay above a foot deep, on several parts of the high roads, and millions were destroyed by the wheels of the carriage. Dr. Shaw says, that he saw them in such multitudes in Barbary, in the middle of April, that in the heat of the day, when they formed themselves into large bodies, they appeared like a succession of clouds darkening the sun: in June the new broods made their appearance; on being hatched, they collected together in compact bodies of several hundred yards square; and marching directly forward, climbed over trees, walls and houses, ate up every plant in their way, and let nothing escape. The inhabitants made trenches and filled them with water; they also placed quantities of combustible matter in rows and set them on fire; but in vain, for the trenches were quickly filled up and the fires extinguished by the vast numbers that succeeded each other.
“Strong winds, which can alone free a country from this plague, have several times blown large swarms over the central part of Europe, and even to England; and it was a ‘mighty west wind,’ which formerly carried them away from Egypt and cast them into the Red Sea.” I asked if these insects were really eatable, as St. John is said to have lived on locusts in the wilderness?
“As it is well known,” said my uncle, “that locusts have in all ages been eaten in the east, and are still esteemed a great delicacy in Barbary as well as in the south of Africa, some commentators have endeavoured to prove that St. John did eat them in the wilderness. But the word translated locusts, signifies also pods or seed-vessels of trees. The pods of some of the Robinia and Gleditsia tribes are considered in Syria to be sweet and nourishing; and it is, I believe, generally supposed that they were the food alluded to in the Gospels.”
29th.—In our genius conversation to-day, several people were mentioned on each side: Mary quoted a passage from Johnson’s Lives of the Poets respecting Denham, who, he says, was “considered at Oxford as a dreaming young man, given more to cards and dice than to study;—he gave no prognostics of his future eminence, nor was suspected to conceal, under sluggishness and idleness, a genius born to improve the literature of his country.” “Of Swift, too,” continued Mary, “there appears no early proof of genius or diligence; for when at the usual time he claimed a bachelorship of arts, he was found by the examiners too conspicuously deficient for regular admission—and at last obtained his degree by special favour; a term used, as Johnson says, in the university of Dublin, to denote want of merit.” It is probable, therefore, that new circumstances combined together afterwards to bring out the powers possessed by these celebrated men; and I am sure, mamma, this little perpetual argument serves to bring out several very entertaining biographical facts.
Haydn, the famous composer, was the son of a wheelwright; such an employment was not likely to lead to the cultivation of music, and we might be tempted to consider him as a natural genius; but it appears that his father played on the harp, and on holidays used to accompany his wife while she sang. Whenever this little domestic concert took place, the child, with two pieces of wood in his hands, to represent a violin and a bow, pretended also to accompany his mother’s voice; and to the very close of his life, this great musician used to perform with delight the airs which she had then sung. A cousin of theirs, a schoolmaster, came to see them, and being well pleased with the boy’s talents, proposed to educate him. His parents accepted the offer; and at school, having discovered a tambourine, an instrument which has but two tones, he succeeded in forming a kind of air, which attracted the attention of all who came to the school-house. He was then taught to sing at the parish desk, and was soon noticed by Reüter, who tried him with a difficult shake, and who was so delighted with the child’s execution, that he emptied a plate of cherries into his pocket. He was eight when admitted to the choir of St. Stephen, at Vienna, and from that time practised above sixteen hours a day. “In all this,” says Mary, “we see the natural effect of circumstances, and no mark of what is called absolute genius.”
30th.—Colonel Travers was not present at our conversation about the locusts; but on its being alluded to this evening, he told us that he had once seen a flight of those creatures which contained such an incredible multitude, that nothing could have persuaded him of the fact, if he had not been an eye-witness to it himself.
Instead of going by sea to India, he went overland, that is, through part of Turkey, Arabia, and Persia; and, in 1811, he happened to be at Smyrna, in Asia Minor, when this extraordinary flight of locusts occurred. He says that for several days stragglers had been passing, but at last the main body came, and in such a dense column, as not indeed to obscure the sun, but to produce a curious quivering light. He thinks the lines in which they appeared to fly were about one foot asunder, and that locust followed locust at the distance of three feet. They came in a steady, undeviating direction from south to north, and continued to pass, without any diminution of their numbers, for three successive days and nights. The breadth of this prodigious column was at least forty miles, for a messenger who had been dispatched by the consul to the pasha of Sardis, passed through them all the way, both going and returning. Caroline immediately produced the map of Asia Minor, and we found that Sardis is fully that distance from Smyrna, and that its direction is just at right angles to the direction of their flight.
My uncle was greatly interested by the Colonel’s account of this remarkable swarm, and proposed that we should endeavour to make some estimate of the number of locusts of which it consisted. We all took out our pencils and went to work. In the first place, the breadth of the column was 40 miles, or 70,400 yards; and as their ranks were a foot apart, we have 211,200 for the number of locusts at each foot of elevation. Colonel T. was then examined as to the entire height; he thinks it must have been much above 300 yards, for on looking upwards with his pocket telescope, he could see them like little specks glittering in the sun. We contented ourselves with the 300, and taking them also at a foot apart, there were of course 900 locusts in height, by which we multiplied the former number, and the product was 190,080,000. Now, mamma, for the length of the column: he says there was a gentle breeze from the southward, with which, and their own velocity, he thinks that they were travelling at the rate of about seven miles in an hour, and that they succeeded each other at an average distance of three feet. In each mile, then, there were 1760, and in seven miles, 12,320, which, multiplied by 72, the number of hours in the three days which the flight continued, gives 887,040 for the number in each line of the column; and this, finally multiplied by the 190 millions, gives the almost inconceivable total of 168,608,563,200,000 in this one swarm of locusts!
“I should like to know,” said Mary, “the exact size of these creatures.”
The Colonel said that he could not answer exactly, without referring to his journals, which were in town, but that he imagined they were about the same size as a large grasshopper: “But why do you want their exact dimensions?”
