After the corn was threshed, or rather trodden out, the oxen had to draw it home in carts. These were but slight improvements on the threshing-sledge, and were simply trays or shallow boxes on a pair of wheels. As the wheels were merely slices cut from the trunk of a tree, and were not furnished with iron tires, they were not remarkable for roundness, and indeed, after a little time, were worn into rather irregular ovals, so that the task of dragging a cart over the rough roads was by no means an easy one. And, as the axle was simply a stout pole fastened to the bottom of the cart, and having its rounded ends thrust through holes in the middle of the wheels, the friction was enormous. As, moreover, oil and grease were far too precious luxuries to be wasted in lubricating the axles, the creaking and groaning of the wheels was a singularly disagreeable and ear-piercing sound. [Illustration: TREADING OUT CORN. "_Thou shalt not muzzle the ox when he treadeth out the corn._"--(DEUT. xxv. 4.)] The common hackery of India is a good example of the carts mentioned in the Scriptures. As with the plough, the cart was drawn by a couple of oxen, connected by the yoke. The two kinds of cart, namely, the tray and the box, are clearly indicated in the Scriptures. The new cart on which the Ark was placed when it was sent back by the Philistines (see 1 Sam. vi. 7) was evidently one of the former kind, and so was that which was made twenty years afterwards, for the purpose of conveying the Ark to Jerusalem. The second kind of cart is mentioned by the Prophet Amos (ch. ii. 13), "Behold, I am pressed under you, as a cart is pressed that is full of sheaves," reference being evidently made to heaping up of the sheaves in the cart, and pressing them down, as is done at the present day. That oxen were also employed as beasts of burden is shown by the passage in 1 Chron. xii. 40, "Moreover, they that were nigh them, even unto Issachar, and Zebulun, and Napthali, brought bread on asses, and on camels, and on mules, and on oxen." Although the cattle were evidently better tended in the olden times than at present, those animals which were used for agriculture seem to have passed rather a rough life, especially in the winter time. It is rather curious that the Jews should have had no idea of preserving the grass by making it into hay, as is done in Europe. Consequently the chief food of the cattle was the straw and chaff which remained on the threshing-floor after the grain had been separated. See Isa. xxx. 23: "In that day shall thy cattle feed in large pastures. The oxen likewise, and the young asses that ear the ground shall eat clean provender, which hath been winnowed with the shovel and with the fan."
