But what the inventions of the nineteenth century were and what they have done for Humanity, is a chapter that must be read by all those now living or to come who wish to learn the history of their race. It is a story which gathers up all the threads of previous centuries and weaves them into a fabric which must be used in all the coming ages in the attainment of their comforts, their adornments, and their civilisations.
To enumerate all the inventions of the century would be like calling up a vast army of men and proclaiming the name of each. The best that can be done is to divide the wide field into chapters, and in these chapters give as best one may an idea of the leading inventions that have produced the greatest industries of the World.
CHAPTER II.
AGRICULTURE AND ITS IMPLEMENTS
The Egyptians were the earliest and greatest agriculturists, and from them the art was learned by the Greeks. Greece in the days of her glory greatly improved the art, and some of her ablest men wrote valuable treatises on its different topics. Its farmers thoroughly ploughed and fertilised the soil, used various implements for its cultivation, paid great attention to the raising of fruits, – the apple, pear, cherry, plum, quince, peach, lemon, fig and many other varieties suitable to their climate, and improved the breeds of cattle, horse and sheep. When, however, social pride and luxurious city life became the dominant passions, agriculture was left to menials, and the art gradually faded with the State. Rome in her best days placed farming in high regard. Her best writers wrote voluminously on agricultural subjects, a tract of land was allotted to every citizen, which was carefully cultivated, and these citizen farmers were her worthiest and most honoured sons. The condition and needs of the soil were studied, its strength replenished by careful fertilisation, and it was worked with care. There were ploughs which were made heavy or light as the different soils required, and there were a variety of farm implements, such as spades, hoes, harrows and rakes. Grains, such as wheat, barley, rye and oats, were raised, a variety of fruits and vegetables, and great attention paid to the breeding of stock. Cato and Varro, Virgil and Columella, Pliny and Palladius delighted to instruct the farmer and praise his occupation.
But as the Roman Empire grew, its armies absorbed its intelligent farmers, the tilling of the soil was left to the menial and the slave, and the Empire and agriculture declined together.
Then came the hordes of northern barbarians pouring in waves over the southern countries and burying from sight their arts and civilisation. The gloom of the middle ages then closed down upon the European world. Whatever good may have been accomplished in other directions by the crusades, agriculture reached its lowest ebb, save in those instances where the culture of the soil received attention from monastic institutions.
The sixteenth century has been fixed upon as the time when Europe awoke from its long slumber. Then it was after the invention of the printing press had become well established that publications on agriculture began to appear. The Boke of Husbandrie, in 1523, by Sir Anthony Fitzherbert; Thomas Tusser's Five Hundred Points of Good Husbandry; Barnaby Googe's The Whole Art of Husbandry; The Jewel House of Art and Nature, by Sir Hugh Platt; the English Improver of Walter Blithe, and the writings of Sir Richard Weston on the husbandry of Brabant and Flanders, were the principal torches by which the light on this subject was handed down through the sixteenth and seventeenth centuries. Further awakening was had in the eighteenth century, the chief part of which was given by Jethro Tull, an English agriculturist, who lived, and wrote, and laboured in the cause between 1680 and 1740. Tull's leading idea was the thorough pulverisation of the soil, his doctrines being that plants derived their nourishment from minute particles of soil, hence the need of its pulverisation. He invented and introduced a horse hoe, a grain drill, and a threshing machine.
Next appeared Arthur Young, of England, born in 1741, whose life was extended into the 19th century, and to whom the world was greatly indebted for the spread of agricultural knowledge. He devoted frequent and long journeys to obtaining information on agricultural subjects, and his writings attracted the attention and assistance of the learned everywhere. His chief work was the making known widely of the beneficial effects of ammonia and ammoniacal compounds on vegetation. Many other useful branches of the subject, clearly treated by him, are found in his Annals of Agriculture. It was this same Arthur Young with whom Washington corresponded from his quiet retreat at Mount Vernon. After the close of the War of Independence in 1783 and before the adoption of the Constitution in 1789 and his elevation to the Presidency in that year, Washington devoted very much of his time to the cultivation of his large estate in Virginia. He took great interest in every improvement in agriculture and its implements. He invented a plough and a rotary seed drill, improved his harrows and mills, and made many inquiries relative to the efficacy of ploughs and threshing machines made in England and other parts of Europe. It was during this period that he opened an interesting correspondence with Young on improvements in agriculture, which was carried on even while he was President, and he availed himself of the proffer of Young's services to fill an order for seeds and two ploughs from a London merchant. He also wrote to Robert Cary & Co., merchants in London, concerning an engine he had heard of as being constructed in Switzerland, for pulling up trees and their stumps by the roots, and ordered one to be sent him if the machine were efficient.
Jefferson, Washington's great contemporaneous statesman and Virginia planter, and to whom has been ascribed the chief glory of the American patent system, himself also an inventor, enriched his country by the full scientific knowledge he had gained from all Europe of agricultural pursuits and improvements.
The progress of the art, in a fundamental sense, that is in a knowledge of the constituents, properties, and needs of the soil, commenced with the investigations of Sir Humphry Davy at the close of the 18th century, resulting in his celebrated lectures before the Board of Agriculture from 1802 to 1812, and his practical experiments in the growth of plants and the nature of fertilisers. Agricultural societies and boards were a characteristic product of the eighteenth century in Europe and America. But this birth, or revival of agricultural studies, the enthusiastic interest taken therein by its great and learned men, and all its valuable publications and discoveries, bore comparatively little fruit in that century. The ignorance and prejudice of the great mass of farmers led to a determined, and in many instances violent resistance to the introduction of labour-saving machinery and the practical application of what they called "book-farming." A fear of driving people out of employment led them to make war upon new agricultural machines and their inventors, as they had upon weaving and spinning inventions. This war was more marked in England than elsewhere, because there more of the new machines were first introduced, and the number of labourers in those fields was the greatest. In America the ignorance took the milder shape of contempt and prejudice. Farmers refused, for instance, to use cast-iron ploughs as it was feared they would poison the soil.
So slow was the invention and introduction of new devices, that if Ruth had revisited the earth at the beginning of the nineteenth century, she might have seen again in the fields of the husbandmen everywhere the sickle of the reapers behind whom she gleaned in the fields of Boaz, heard again the beating on the threshing floor, and felt the old familiar rush of the winnowing wind. Cincinnatus returning then would have recognised the plough in common use as about the same in form as that which he once abandoned on his farm beyond the Tiber.
But with the spread of publications, the extension of learning, the protection now at last obtained and enforced for inventions, and with the foundations laid and the guide-posts erected in nearly every art and science by previous discoverers, inventors and writers, the century was now ready to start on that career of inventions which has rendered it so glorious.
As the turning over and loosening of the sod and the soil for the reception of seed was, and still is the first step in the art of agriculture, the plough is the first implement to be considered in this review.
