In case of small frames, like the ones I have described as most desirable to my mind, I should prefer that the rack might hold four frames. Mr. O. J. Hetherington has found that winding the rack with fine wire, serves better than wire-cloth to resist the combs, while permitting the honey to pass. The rack should set so low in the can that no honey would ever be thrown over the top to daub the person using the machine. I think that a wire basket, with a tin bottom, and made to hook on to the comb-rack (Fig. 58, _a, a_) which will hold pieces of comb not in frames, a desirable improvement to an extractor. Such baskets are appended to the admirable extractor (Fig. 58) made by Mr. B. O. Everett, of Toledo, Ohio, which, though essentially like the extractor of Mr. A. I. Root, has substantial improvements, and is the cheapest, and I think the best extractor, that I have used or seen. [Illustration: Fig. 59.] I have tried machines where the sides of the rack (Fig. 59) inclined down and in, for the purpose of holding pieces of comb, but found them unsatisfactory. The combs would not be sustained. Yet, if the frames were long and narrow, so that the end of the frame would have to rest on the bottom of the rack, instead of hanging as it does in the hive, such an incline might be of use to prevent the top of the frame from falling in, before we commence to turn the machine. The inside, if metal, which is lighter and to be preferred to wood, as it does not sour or absorb the honey, should be either of tin or galvanized iron, so as not to rust. A cover to protect the honey from dust, when not in use, is very desirable. The cloth cover, gathered around the edge by a rubber, as made by Mr. A. I. Root, is excellent for this purpose. As no capped honey could be extracted, it is necessary to uncap it, which is done by shaving off the thin caps. To do this, nothing is better than the new Bingham & Hetherington honey knife (Fig. 60). After a thorough trial of this knife, here at the College, we pronounce it decidedly superior to any other that we have used, though we have several of the principal knives made in the United States. It is, perhaps, sometimes desirable to have a curved point (Fig. 61), though this is not at all essential. [Illustration: Fig. 60.] [Illustration: Fig. 61.] USE OF THE EXTRACTOR.
