Cherry Valley, N. Y., Jan. 5, 1879.--I received the knives all right, and on account of their superiority I feel that you, and bee-keepers as well, are entitled to a report on them. For my own use I much prefer them to any knife I have ever uncapped with, for the reason that I can uncap much more honey. A better test is in the hands of three or four of my men who used them for several consecutive days, and without exception pronounced them the best knives I owned. One even went so far as to insist that he could uncap one-third; faster than with any other knife I had, and when uncapping prize boxes he satisfactorily demonstrated it. You may send me half a dozen for my own apiaries. J. E. Hetherington. The Michigan Bee-Keepers' Association especially recommends the Bingham & Hetherington Honey Knife and the Bingham Smoker. =Muth's All-Metal Honey Extractor.= Patented Sept. 24th, 1878. [Illustration] Every bee-keeper is aware of the advantages afforded by a judicious use of the Honey Extractor. The inventions of the movable comb frames by Rev. L. L. Langstroth, and that of the Honey Extractor by Major v. Hruschka, are the greatest achievements in the apiary. They have made it possible to multiply our practical results tenfold, and to put a system to bee-culture. Quite a number of different styles of extractors have been made since their first invention, about 10 or 12 years ago. Mine differs from others by the slanting sides of the comb basket, arranged above a receptacle for honey in the same tin can, and with a substantial gearing which requires not more than the strength of a child to work the machine all day with ease; frames of different sizes, but smaller than the comb-basket, and pieces of comb without a frame, are placed against the slanting sides, and without being fastened, emptied of their contents completely, and, to the uninitiated, in an incredulous short time. The cells having a downward tendency, empty more readily, both in top and bottom of frames, than when in a vertical position, as every practical test will show, and the flying of honey, in the shape of a fine spray, over the top of the can is prevented. There is a receptacle for 60 lbs. or more of honey in the extractor, according to the depth of the comb-basket, which can be made of any size desired--for instance, for Langstroth's and Quinby's frames, the comb-basket is 18½ inches deep, and the receiver holds about 65 lbs. of honey. If the American frame is the largest to be extracted, the comb-basket is only 12 inches deep, while the extractor holds about 140 lbs. of honey before it touches the revolving basket and needs to be drawn off by the iron faucet at the bottom. My standard size of comb-basket is 12¼ × 18½ inches, and admits the Langstroth, Quinby and American frames. When ordering, please state the largest size of frames used.
