Han-kow is a great centre of trade. Frequently the mouth of the Han is so crowded with junks that the river is entirely covered, and you may walk for hours by merely stepping from one boat to another. The upper Yang-tse and the Han bring down large quantities of tea, furs, silk, wax, and other products, both for home use and for export. There are heavy exports of tea from Han-kow direct to England, and every year steamers go there to load with cargoes, which they take to London as rapidly as possible. Our friends were told that there was a large trade in brick tea, which was prepared for the Russian market; and as the boys were anxious to see the process of preparation, a visit to one of the factories was arranged. Frank made a note of what he saw and wrote it out as follows: [Illustration: A STREET IN HAN-KOW.] "The dry tea is weighed out into portions for single bricks, and each portion is wrapped in a cloth and placed over a steam-boiler. When it is thoroughly steamed, it is poured into a mould and placed beneath a machine, which presses it into the required shape and size. Some of the machines are worked by hand, and others by steam. Both kinds are very rapid and efficient, and we could not see that the steam had much advantage. Five men working a hand machine, and receiving twenty cents each for a day's labor, were able to press six bricks a minute, as we found by timing them with our watches. The steam press worked only a little faster, and the cost of fuel must have been about equal to that of human muscle. "Only the poorest kind of tea is made into bricks, and each brick is about six inches wide, eight inches long, and one inch thick. After it has been pressed, it is dried in ovens; and when it is thoroughly dried and ready for packing, it is weighed, to make sure that it is up to the required standard. All bricks that are too light are thrown out, to be mixed up again and done over. Nearly all of this business is in Russian hands, for the reason that this kind of tea is sold only in Russia." Doctor Bronson arranged that the party should visit Wo-chang and see a famous pagoda that stood on the bank of the river. There was not a great deal to see after they got there, as the place was not in good repair, and contained very little in the way of statues and idols. The stairways were narrow and dark, and the climb to the top was not accomplished without difficulty. Afterwards they went through the principal streets, and visited the shops, which they found much like those of Shanghai and Chin-kiang. The people showed some curiosity in looking at the strangers--more than they had found farther down the river--for the reason, doubtless, that fewer foreigners go there. [Illustration: WO-CHANG.]
