Performance of B. M. W. 185-Horsepower Airplane Engine

Description: "This report deals with the results of a test made upon a B. M. W. Engine in the altitude chamber of the Bureau of Standards, where controlled conditions of temperature and pressure can be made to simulate those of the desired altitude. A remarkably low value of fuel consumption - 041 per B. H. P. hour - is obtained at 1,200 revolutions per minute at an air density of 0.064 pound per cubic foot and a brake thermal efficiency of 33 per cent and an indicated efficiency of 37 per cent at the above… more

Spontaneous Combustion of Hydrogen

Description: It is shown by the author's experiments that hydrogen which escapes to the atmosphere through openings in the system may burn spontaneously if it contains dust. Purely thermal reasoning can not account for the combustion. It seems to be rather an electrical ignition. In order to determine whether the cause of the spontaneous ignition was thermo-chemical, thermo-mechanical, or thermo-electrical, the experiments in this paper were performed.

Beekeeping in the Clover Region

Description: "Beekeeping methods suitable for the clover region are well developed but many beekeepers of this region are failing to obtain the full available honey crop because of deficiencies in their practice. A system of management is here given which will result in a full crop from these sources. The variation in the value of the clovers to the beekeeper is also discussed and the methods to be followed in bringing the clover region back to its former prominence in honey production are outlined." -- p. 2 more

Beekeeping in the Buckwheat Region

Description: "The production of the full honey crop from buckwheat requires a plan of apiary management quite different from that of most other beekeeping regions. A system of management is here given which will result in a full honey crop and at the same time control European foulbrood, which is so prevalent in the buckwheat region. Methods are also given which may be used in case the clovers are valuable as sources of nectar." -- p. 2

Beekeeping in the Tulip-Tree Region

Description: "Many thousand colonies of bees occur in the region where the tulip-tree is abundant but the honey crop from tulip-tree flowers inconsiderable.

The Sugar-Beet Nematode in the Western States

Description: "The sugar-beet nematode is one of the most serious of the beet pests. It appears to have been imported with some shipments of beet seed many years ago. It has been found widely scattered in four of the western sugar-beet States and probably exists in other States where beets have been grown for several years. The sugar-beet nematode is the cause of a great deal of loss to the beet grower through reduction of his tonnage, and of a corresponding amount of loss to the sugar producer through reduc… more

Green Manuring

Description: "Green manuring means turning under suitable crops to enrich the soil. Such crops may be turned under green or when ripe. Green manuring adds organic matter and, directly or indirectly, nitrogen to the soil. Leguminous crops are most desirable for green manuring, since they add to the soil nitrogen gathered from the air in addition to the organic matter which they carry. Besides the nitrogen in the legumes turned under, an additional supply of nitrogen is fixed in the soil by the action of bact… more
