In 1851 Mr. Munn issued a second edition of his book, in the preface of which I find the following: "Having materially simplified the bar-frame hive, by forming the 'oblong bar-frames' into 'triangular frames,' and making them lift out of the top, instead of the back of the bee-box, I have republished the pamphlet." The triangular hive (Fig. 112) is described and figured, and is the same as found illustrated in Munn's "Bevan on the Honey Bee." This hive, although a possible improvement on the other, is costly, intricate, and still very impracticable. In the price-list of J. Pettitt, Dover, England, 1864, I find this hive priced at £3 3s., or about $15.00. From the figure we learn that there were some wide spaces about the frames. These would of course be filled with comb, and render the hives entirely unsuitable for common use. That this hive lacked the essential requisites to success is evident from words penned by the inventor in 1863: "The hive matters little if the pasturage is good." And it is easy to see from the complex arrangement of the frames, and the wide spaces about them, that as Mr. Munn said, referring to his hive, "When left to themselves the bees shut up the shop." Had invention stopped with Major Munn's hive, we should to-day be using the old box hive, and sighing in vain for a better. Neighbour well says (3d edition, p. 129): "Probably the reason of the invention's failure was the expensiveness of the Major's fittings, which make the hive appear more like some astronomical instrument, than a box for bees. Be this as it may, there was no such thing as a frame hive in use in England till 1860." It would seem strange, that after going so far Major Munn should have failed to give bee-keepers a hive of value. Yet with his view that smoke injured the bees and brood (2d edition, p. 21), we can readily see, that with his hive and black bees, a man would need the skin of a rhinoceros, and nerves of brass, to do much by way of actual manipulation for practical purposes. It has been truly said that "The Huber hive can be used with far greater ease and safety, by a novice, than can Munn's." It will be seen by reference to "Bee Culture with Movable Frames," published by Pastor George Kleine, Hanover, Germany, in 1853, p. 5, that a druggist by the name of Schmidt, in a work which he published in Freiburg, in 1851, entitled, "The New Bee Homes," describes a hive with the Huber leaves having prolonged tops which hung on rabbets, much as do our frames. These Huber leaves were close-fitting, and so not practical. Kleine regarded this as inferior to the Huber hive, in that the combs must be taken out from above. With a side opening he thinks it would be a material improvement. It is evident from Kleine's work, that he knew nothing either of Munn or his hive.
