Hop Production in the United States
The distribution of the area of hop-cultivation in the United States showed great changes during the last decades of the 19th and the first decade of the 20th century. During the earlier portion of that period New York was the chief hop-growing state of the Union, but toward the end of it a great extension of hop-growing took place on the Pacific coast (in the states of Oregon, California and Washington), where the richness of the soil and mildness of the climate are favourable to the bines.
The average annual produce of hops in the United States from 1900 to 1906 was 423,471 cwt.; of this quantity 80% was raised in the three states of the Pacific coast, where the yield per acre is much larger than in New York. In the latter state the yield does not appear to exceed 5 or 6 cwt. per acre, whereas in Oregon it is 9 or 10 cwt., and in Washington and California from 12 to 14 cwt. The average annual export (chiefly to Great Britain) in the years from 1899 to 1905 was 108,400 cwt.; the average import (chiefly from Germany) is about 50,000 cwt.
Hop Cultivation
As the county of Kent has always taken the lead in hop-growing in England, and as it includes about two-thirds of the hop acreage of the British Isles, the recent developments in hop cultivation cannot be better studied than in that county. They were well summarized by Mr Charles Whitehead in his sketch of the agriculture of Kent,[2] wherein he states that the hop grounds—or hop gardens, as they are called in Kent—of poor character and least suitable for hop production have been gradually grubbed since 1894, on account of large crops, the importation of hops and low prices. At the beginning of the 19th century there were 290 parishes in Kent in which hops were cultivated. A century later, out of the 413 parishes in the county, as many as 331 included hop plantations. The hops grown in Kent are classified in the markets as “East Kents,” “Bastard East Kents,” “Mid Kents” and “Wealds,” according to the district of the county in which they are produced. The relative values of these four divisions follow in the same order, East Kents making the highest and Wealds the lowest rates. These divisions agree in the main with those defined by geological formations. Thus, “East Kents” are grown upon the Chalk, and especially on the outcrop of the soils of the London Tertiaries upon the Chalk. “Bastard East Kents” are produced on alluvial soil and soils formed by admixtures of loam, clay-loams, chalk, marl and clay from the Gault, Greensand and Chalk formations. “Mid Kents” are derived principally from the Greensand soils and outcrops of the London Tertiaries in the upper part of the district. “Wealds” come from soils on the Weald Clay, Hastings Sand and Tunbridge Wells Sand. As each “pocket” of hops must be marked with the owner’s name and the parish in which they were grown, buyers of hops can, without much trouble, ascertain from which of the four divisions hops come, especially if they have the map of the hop-growing parishes of England, which gives the name of each parish. There has been a considerable rearrangement of the hop plantations in Kent within recent years. Common varieties as Colegate’s, Jones’s, Grapes and Prolifics have been grubbed, and Goldings, Bramlings and other choice kinds planted in their places. The variety known as Fuggle’s, a heavy-cropping though slightly coarse hop, has been much planted in the Weald of Kent, and in parts of Mid Kent where the soil is suitable. In very old hop gardens, where there has been no change of plant for fifty or even one hundred years in some instances, except from the gradual process of filling up the places of plants that have died, there has been replanting with better varieties and varieties ripening in more convenient succession; and, generally speaking, the plantations have been levelled up in this respect to suit the demand for bright hops of fine quality. A recent classification[3] of the varieties of English hops arranges them in three groups: (1) early varieties (e.g. Prolific, Bramling, Amos’s Early Bird); (2) mid-season or main-crop varieties (e.g. Farnham Whitebine, Fuggle’s, Old Jones’s, Golding); (3) late varieties (e.g. Grapes, Colgate’s).
The cost of cultivating and preparing the produce of an acre of hop land tends to increase, on account of the advancing rates of wages, the intense cultivation more and more essential, and the necessity of freeing the plants from the persistent attacks of insects and fungi. In 1893 Mr Whitehead estimated the average annual cost of an acre of hop land to be £35, 10s., the following being the items:—
| Manure (winter and summer) | £6 | 10 | 0 |
| Digging | 0 | 19 | 0 |
| Dressing (or cutting) | 0 | 6 | 0 |
| Poling, tying, earthing, ladder-tying, stringing, lewing | 2 | 3 | 0 |
| Shimming, nidgeting, digging round and hoeing hills | 3 | 0 | 0 |
| Stacking, stripping, making; bines, &c. | 0 | 17 | 0 |
| Annual renewal of poles | 2 | 10 | 0 |
| Expense of picking, drying, packing, carriage, sampling, | |||
| selling, &c., on average crop of, say, 7 cwt. per acre | 10 | 5 | 0 |
| Rent, rates, taxes, repairs of oast and tacks, interest on capital | 6 | 0 | 0 |
| Sulphuring | 1 | 0 | 0 |
| Washing (often two, three or four times) | 2 | 0 | 0 |
| ————— | |||
| Total | £35 | 10 | 0 |
Seven years later the average cost per acre in Kent had risen to quite £37.
The hops in Kent are usually planted in October or November, the plants being 6 ft. apart each way, thus giving 1210 hills or plant-centres per acre. Some planters still grow potatoes or mangels between the rows the first year, as the plants do not bear much until the second year; but this is considered to be a mistake, as it encourages wire-worm and exhausts the ground. Many planters pole hop plants the first year with a single short pole, and stretch coco-nut-fibre string from pole to pole, and grow many hops in the first season. Much of the hop land is ploughed between the rows, as labour is scarce, and the spaces between are dug afterwards. It is far better to dig hop land if possible, the tool used being the Kent spud. The cost of digging an acre ranges from 18s. to 21s. Hop land is ploughed or dug between November and March. After this the plants are “dressed,” which means that all the old bine ends are cut off with a sharp curved hop-knife, and the plant centres kept level with the ground.
