Jamaica Plains, near Boston, made and used movable frame hives prior to 1852. The wife of Dr. Robinson testified that her husband bought a right to use the Langstroth hive, and with it made his first movable frames. Every claim, both at home and abroad, to the invention of a practical movable frame hive, prior to that of Mr. Langstroth, when examined, is found to have no substantial foundation. All previous hives were plainly inferior to the improved Huber hive as described in Bevan, p. 106. It is a sad blot upon American apiculture, that he who raised it to the proud height which it occupies to-day, should have been shamefully defrauded of the just reward for his great invention. But it gives me the greatest pleasure to state, that by no possible word could I gather that Mr. Langstroth feels any bitterness towards those who seem wilfully to have stolen his invention, while with a mantle of charity, great as is his noble heart, he covers the thousands who either thought he had no valid claim, or else that the purchase of a right from others, entitled them to his invention. As an inventor and writer on apiculture, Mr. Langstroth will ever be held in grateful memory. How earnestly will American apiarists desire that he may be spared to us until he completes his autobiography, that we may learn how he arrived at his great discovery, and may study the methods by which he gleaned so many rich and valuable truths. * * * * * LECANIUM TULIPIFERÆ--Cook. In the summer of 1870, this louse, which, so far as I know, has never yet been described, and for which I propose the above very appropriate name, tulipiferæ--the Lecanium of the tulip tree--was very common on the tulip trees about the College lawns. So destructive were they that some of the trees were killed outright, others were much injured, and had not the lice for some unknown reason ceased to thrive, we should soon have missed from our grounds one of our most attractive trees. Since the date above given, I have received these insects, through the several editors of our excellent bee papers, from many of the States, especially those bordering the Ohio River. In Tennessee they seem very common, as they are often noticed in abundance on the fine stately tulip trees of that goodly State--in the South this tulip tree is called the poplar, which is very incorrect, as it is in no way related to the latter. The poplar belongs to the willow family; the tulip to the magnolia, which families are wide apart. In Pennsylvania the louse has been noticed on the cucumber tree--Magnolia acuminata.
