There was a man born blind, who had several apprentices in his own condition; their employment was to mix colors for painters, which their master taught them to distinguish by feeling and smelling. It was indeed my misfortune to find them at that time not very perfect in their lessons, and the professor himself happened to be generally mistaken. This artist is much encouraged and esteemed by the whole fraternity.
In another apartment, I was highly pleased with a projector who had found a device of ploughing the ground with hogs, to save the charges of ploughs, cattle, and labor. The method is this: In an acre of ground you bury at six inches’ distance, and eight deep, a quantity of acorns, dates, chestnuts, and other mast or vegetables whereof these animals are fondest; then you drive six hundred or more of them into the field, where in a few days they will root up the whole ground in search of their food, and make it fit for sowing, at the same time manuring it with their dung; it is true upon experiment they found the charge and trouble very great, and they had little or no crop. However, it is not doubted that this invention may be capable of great improvement.
I went into another room, where the walls and ceiling were all hung round with cobwebs, except a narrow passage for the artist to go in and out. At my entrance, he called aloud to me not to disturb his webs. He lamented the fatal mistake the world had been so long in of using silkworms, while he had such plenty of domestic insects who infinitely excelled the former, because they understood how to weave as well as spin. And he proposed further, that by employing spiders, the charge of dyeing silks should be wholly saved; whereof I was fully convinced when he showed me a vast number of flies most beautifully colored, wherewith he fed his spiders, assuring us that the webs would take a tincture from them; and as he had them of all hues, he hoped to fit everybody’s fancy, as soon as he could find proper food for the flies, of certain gums, oils, and other glutinous matter, to give a strength and consistence to the threads.
There was an astronomer who had undertaken to place a sundial upon the great weathercock on the townhouse, by adjusting the annual and diurnal motions of the earth and sun, so as to answer and coincide with all accidental turnings by the wind.
I visited many other apartments, but shall not trouble my reader with all the curiosities I observed, being studious of brevity.
I had hitherto seen only one side of the academy, the other being appropriated to the advancers of speculative learning, of whom I shall say something when I have mentioned one illustrious person more, who is called among them “the universal artist.” He told us he had been thirty years employing his thoughts for the improvement of human life. He had two large rooms full of wonderful curiosities, and fifty men at work. Some were condensing air into a dry tangible substance, by extracting the niter, and letting the aqueous or fluid particles percolate; others softening marble for pillows and pincushions; others petrifying the hoofs of a living horse to preserve them from foundering. The artist himself was at that time busy upon two great designs; the first to sow land with chaff, wherein he affirmed the true seminal virtue to be contained, as he demonstrated by several experiments which I was not skillful enough to comprehend. The other was, by a certain composition of gums, minerals, and vegetables, outwardly applied, to prevent the growth of wool upon two young lambs; and he hoped in a reasonable time to propagate the breed of naked sheep all over the kingdom.
We crossed a walk to the other part of the academy, where, as I have already said, the projector in speculative learning resided.
The first professor I saw was in a very large room, with forty pupils about him. After salutation, observing me to look earnestly upon a frame, which took up the greatest part of both the length and breadth of the room, he said perhaps I might wonder to see him employed in a project for improving speculative knowledge by practical and mechanical operations. But the world would soon be sensible of its usefulness, and he flattered himself that a more noble exalted thought never sprang in any other man’s head. Every one knew how laborious the usual method is of attaining to arts and sciences; whereas by his contrivance the most ignorant person, at a reasonable charge, and with a little bodily labor, may write books in philosophy, poetry, politics, law, mathematics, and theology, without the least assistance from genius or study. He then led me to the frame, about the sides whereof all his pupils stood in ranks. It was twenty feet square, placed in the middle of the room. The superficies was composed of several bits of wood, about the bigness of a die, but some larger than others. They were all linked together by slender wires. These bits of wood were covered on every square with paper pasted on them; and on these papers were written all the words of their language in their several moods, tenses, and declensions, but without any order. The professor then desired me to observe, for he was going to set his engine at work. The pupils, at his command, took each of them hold of an iron handle, whereof there were forty fixed round the edges of the frame, and giving them a sudden turn, the whole disposition of the words was entirely changed. He then commanded six-and-thirty of the lads to read the several lines softly as they appeared upon the frame; and where they found three or four words together that might make part of a sentence, they dictated to the four remaining boys, who were scribes. This work was repeated three or four times; and at every turn the engine was so contrived, that the words shifted into new places, as the square bits of wood moved upside down.
Six hours a day the young students were employed in this labor; and the professor showed me several volumes in large folio, already collected, of broken sentences, which he intended to piece together, and out of those rich materials to give the world a complete body of all arts and sciences; which, however, might be still improved, and much expedited, if the public would raise a fund for making and employing five hundred such frames in Lagado, and oblige the managers to contribute in common their several collections.
He assured me that this invention had employed all his thoughts from his youth; that he had employed the whole vocabulary into his frame, and made the strictest computation of the general proportion there is in books between the numbers of particles, nouns, and verbs, and other parts of speech.
