These bell glasses are used in the hives before described. The largest is for Nutt's hive; the middle-sized is for our improved cottage hive; the smallest glass is so very small that it is not often used, and we do not recommend it. Bees will generally fill a middle-sized glass quite as soon as one so small as this. TAYLOR'S BELL GLASSES. [Illustration] These glasses have been introduced by Mr. Taylor, and are recommended as preferable to deep narrow glasses. The drawings will show that they are straight at the sides, flat at the top inside, with a knob outside to take hold by, through which is a half-inch opening to admit a ventilating tube. The larger is six inches deep, twelve inches wide; smaller, five inches deep, nine and a half inches wide. [Illustration] The late Mr. J. H. Payne, of Bury, author of the "Bee-keeper's Guide" introduced another glass. It has a three-inch hole in the centre, the purpose of which is to tempt bees to produce additional and larger stores of honey. It is to be used as follows:--When a bell glass is half or quite filled, raise it, and place Payne's glass over the hole of the stock-hive, with the filled glass on it, over the three-inch hole. The bees will bring their combs through, and thus Mr. Payne found that they would store more honey than if the bell glass were removed and another empty one put in its place. Of course, the first glass must be smaller in diameter than Payne's glass, so as to rest upon it. FLAT-TOPPED GLASS. This is a glass super, to be placed on the hive in a similar way to the bell glasses already alluded to. It has the advantages of being straight at the sides, flat at top, and without a knob; so that when filled it may be brought on to the breakfast table, inverted, on a plate. The glass lid shown in the engraving forms a cover, and fits over outside, so as not to interfere with the combs within. These flat-top glasses, like those with a knob, have a hole through which a zinc ventilating tube is inserted. Dimensions, six and three-quarter inches wide, five inches high. [Illustration] GUIDE-COMB FOR GLASSES. In some of our previous allusions to the best mode of inducing bees to commence working in glasses, we have recommended attaching guide-comb. We will now more particularly explain how this attraction can be best applied. We have already shown how bees may be induced to make use of guide-combs fixed to bars, and the same principle is applicable to glasses. These may be filled, with great regularity, by adopting the following directions, which, we believe, have never before appeared in print:--
