An account is given of the development of hop‐picking machines, from their first successful use in California in 1905 to the present day. The principles involved in mechanical picking are described, the English machines being mainly of the stationary vertical type. In consequence of varietal characteristics, the traditional English hops (Goldings, Fuggles) present greater difficulties for mechanical picking than do American varieties; in general, “hard” hops pick more easily than those with “soft” cones, and seedless hops more easily than seeded types. The influence of climate is important, and careful design and running of machines is of first importance if damage is to be avoided and if a clean sample, reasonably free from leaf and strig, is to be produced. Attempts must be made to minimize the present losses of lupulin. Greatly increased mechanical picking is to be expected in the near future, and care must be token to see that a falsely high valuation is not placed on the samples so obtained.
