HOPS.
These are native in this country, being found, growing spontaneously, by many of our rivers. There are four or five varieties, but no preference has been given to any particular one. Moist, sandy loam is the best soil, though good hops may be grown in abundance on any land suitable for corn or potatoes. Plow the land quite deep in autumn; in the spring, harrow the same way it was plowed. Spread evenly over the surface sixteen cords of manure to the acre, if your soil be of ordinary richness; cross-plow as deep as the first plowing; furrow out as for potatoes, four feet apart each way. Plant hops in every other hill of every other row, making them eight feet apart each way. Plant all the remaining hills with potatoes. Four cuttings of running roots of hops should be planted in each hill. Many hop-yards are unproductive on account of being too thick;—less than eight feet each way deprives the vines of suitable air and sun, and prevents plowing them with ease. The first year, they only need to be kept clean of weeds by hoeing them with the potatoes. In the fall of the first year, to prevent injury from hard frosts, put a large shovelful of good manure on the top of each hill. Each spring, before the hops are opened, spread on each acre eight cords of manure; coarse straw manure is preferable. Plow both ways at first hoeing. They require three hoeings, the last when in full bloom in the beginning of August. Open the hops every spring by the middle of May; at the South, by the last of April. This is done by making four furrows between the rows, turning them from the hills; the earth is then removed from the roots with a hoe, and all the running roots cut in with a sharp knife within two inches of the main roots. The tops of the main roots must also be cut in, and covered with earth two inches deep. Set the poles on the first springing of the vines; never have more than two poles in a hill, or more than two vines on a pole, and no pole more than sixteen feet high. Neglect this root-pruning, and multiply poles and crowd them with vines, and you will get very few hops. Select the most thrifty vines for the poles, and destroy all the others. Watch them during the summer, that they do not blow down from the poles. They must be picked as soon as they are ripe, and before frosts. The best picking-box is a wooden bin made of light boards, nine feet long, three feet wide, and two and a half feet deep; the poles are laid across this, and the hops picked into it by hand. In gathering hops, cut the vines two feet from the ground, that bleeding may not injure the roots.
Curing is the most important matter in hop-growing. Hops would all be of one quality, and bring the first price, if equally well cured. The following description (with slight abbreviation) of the process of curing, by William Blanchard, Esq., is, perhaps, as complete as anything that can be obtained. Much depends upon having a well-constructed kiln. For the convenience of putting the hops on the kiln, a side hill is generally chosen for its situation; it should be a dry situation. It should be dug out the same bigness at the bottom as at the top; the side walls laid up perpendicularly, and filled in solid with stone to give it a tunnel form: twelve feet square at the top, two feet square at the bottom, and at least eight feet deep, is deemed a convenient size. On the top of the walls sills are laid, having joists let into them, as for laying a floor, on which laths, about one and a half inches wide, are nailed, leaving open spaces between them three fourths of an inch, over which a thin linen cloth is spread and nailed at the edges to the sills. A board about twelve inches wide is set up on each side of the kiln, on the inner edge of the sill, to form a bin to receive the hops. Fifty pounds, after they are dry, is all such a kiln will hold at once. The larger the stones made use of in the construction of the kiln the better, as it will give a more steady and dense heat. The inside of the kiln should be well plastered with mortar to make it air-tight. Charcoal is the best fuel. Heat the kiln well before putting on the hops; keep a steady and regular heat while drying. Hops must not remain in bulk long after being picked, as they will heat and spoil. Do not stir them while drying. After they are thoroughly dry, remove them into a dry room, and lay in heaps, and not stir unless they are gathering dampness that will change their color; then spread them. This will only occur when they have not been properly dried. They are bagged by laying cloth into a box, so made that it can be removed, and give opportunity to sew up the bag while in the press. The hops are pressed in by a screw. In bulk they will sweat a little, which will begin to subside in about eight days, at which time they should be bagged. If they sweat much and begin to change their color, they must be dried before bagging. The best size for bags is about two hundred and fifty pounds' weight, in a bag about five feet long. Common tow-cloth or Russia-hemp bags are best. Extensive hop-growers build houses over the kiln, that they may be able to use them in wet weather. In this case, keep the doors open as much as possible without letting in the rain. Dried without sufficient air, their color is changed, and their quality and market-value injured. These houses are made much larger than the kiln, in many instances, for the convenience of storing and bagging the hops when dry; in this case, tight partitions should separate the storerooms from the kiln, to avoid dampness from the drying hops.
The form of manuring recommended is contrary to the old practice of putting a little manure only in the hill: that practice exposed vines to decay and destruction by worms, and this does not; our system also produces hops equal to new land.
