Identification De Quelques Megachiles, R. Buysson

Bysson begins the discussion with a general discussion of the nests of Megachile. They place their nests in various places (cavities). The nests are always constructed of pieces of leaves – oval ones on the walls and discs (small) forming partitions between cells and bottom. The appear to choose leaves of certain plants – but are not exclusive. Ordinarily they make more nests with more cells plants – but are not exclusive. Ordinarily they make more nests with more cells than do the Osmia. At least with the following species he noted that in all cases, the eggs to be …
Bulletin No. 74 - Lead Ore In Sugar Beet Pulp, John A. Widtsoe, Lewis A. Merrill
Bulletin No. 74 - Lead Ore In Sugar Beet Pulp, John A. Widtsoe, Lewis A. Merrill
UAES Bulletins
The recent great development of the beet sugar industry in the State of Utah, has made the matter of utilizing the sugar beet pulp an important question for Utah farmers. That beet pulp has a high feeding value, when fed in proper combinations, has been shown conclusively since the establishment of the first beet sugar factory in the State, ten years ago. The experience of other states, and of the beet sugar producing countries of Europe, has likewise demonstrated that beet pulp may be used profitably in the feeding of farm animals. It is doubtlessly true that much is yet …

There are in Utah many lands that will not, for many years to come, be brought under irrigation; and there are many others that probably will never be irrigated. These are usually high-lying lands, often far from large streams, to irrigate which, would require the construction of exceptionally costly reservoirs, dams, and canals. Many Utah valleys are so far removed from the water supply of the State that it is improbable that water will be carried past other thirsting lands to these outlying places. The building of irrigation works is a venture in which profits and losses are considered; and …

Mr. J. Chester Bradley has begun, in the May number of the "Entomological Student," a monographic revision of the Evaniida of North America, a work badly needed by our students. On learning from me that I had several new species in this family, he has requested that I should publish them at once, so that they may be incorporated in his monograph, which will be published in the Transactions of the American Entomological Society of Philadelphia. I begin, therefore, by publishing three new species in Abbe Provancher's rare genus, Pammegischia, a genus suppressed by Dr. Schletterer, but revived in my …

No bulletins have heretofore been issued by the Dairy department of this Station on the special question of the manufacture of dairy products. The main work of the Dairy department has been with the farm end of the dairy problem; viz: the production of milk. This includes the breeding, feeding and management of cows, the raising and developing of the young stock, and the economic disposal of the by-products of the dairy. From information gathered during my first year at the College it was apparent that this foundation work should have first attention. At this time but six to eight …
