[Illustration: JAPANESE ROLLER.] In another place a man was engaged in ploughing. He had a primitive-looking instrument with a blade like that of a large hatchet, a beam set at right angles, and a single handle which he grasped with both hands. It was propelled by a horse which required some one to lead him, but he did not seem to regard the labor of dragging the plough as anything serious, as he walked off very much as though nothing were behind him. Just beyond the ploughman there was a man with a roller, engaged in covering some seed that had been put in for a late crop. He was using a common roller, which closely resembled the one we employ for smoothing our garden walks and beds, with the exception that it was rougher in construction, and did not appear as round as one naturally expects a roller to be. [Illustration: MANURING PROCESS.] Fred saw a man dipping something from a hole in the ground, and asked the Doctor what he was doing. [Illustration: HOW THEY USE MANURE.] The Doctor explained that the hole was a cask set in the ground, and that it probably contained liquid manure. The Japanese use it for enriching their fields. They keep it in these holes, covered with a slight roof to prevent its evaporation as much as possible, and they spread it around where wanted by means of buckets. The great drawback to a walk in a Japanese field is the frequency of the manure deposits, as the odor arising from them is anything but agreeable. Particularly is this so in the early part of the season, when the young plants require a great deal of attention and nourishment. A nose at such times is an organ of great inconvenience. [Illustration: MODE OF PROTECTING LAND FROM BIRDS.] The Doctor went on to explain that the Japanese farmers were very watchful of their crops, and that men were employed to scare away the birds, that sometimes dug up the seed after it was planted, and also ate the grain while it was ripening. The watchmen had pieces of board which they put on frames suspended in the air, and so arranged that they rattled in the wind, and performed a service similar to that of the scare-crow in America. In addition to this mode of making a noise, the watchmen had whistles and clappers, and sometimes they carried small bells which they rang as they walked about. It was the duty of a watchman to keep constantly on the alert, as the birds were full of mischief, and, from being rarely shot at, their boldness and impudence were quite astonishing to one freshly arrived from America, where the use of fire-arms is so general. While Doctor Bronson was explaining about the birds, Fred suddenly gave an exclamation of delight. "Look, look!" said he; "what are those beautiful white birds?" "Oh, I know," answered Frank; "they are storks. I recognize them from the pictures I have seen on fans and screens. I'm sure they are storks." [Illustration: STORKS, DRAWN BY A NATIVE ARTIST.]
