Стр. 1 - IT should be stated at the outset that any discussion of the possibilities or limitations of co-operative marketing must recognize the fact that there is a wide range in what may reasonably be expected of various organizations. Just what they are in any given instance will depend upon a number of factors such as the nature of the commodity, the degree to which private business has already perfected distribution of it, upon the degree to which people are trained in co-operation, and upon whether the...
Стр. 15 - ... conduction. The air near the ground now becomes cooler than the air above and its density becomes increasingly greater. Instead of rising, as did the surface air during the day, its increased density tends to keep it in contact with the ground. Thus over a level plain on a clear, calm night we find a relatively thin layer of cold air near the ground with an increase in temperature up to an altitude of between 300 and 800 feet. Air Drainage. — Over gently sloping ground the force of gravity...
Стр. 15 - Continuoue records of the temperature from 4 pm to 9 am at the base and at different heights above the base of a steep hillside, showing the great differences in temperature that sometimes develop on a clear, still night. Although the temperature at the base was low enough to cause considerable damage to .fruit, the lowest temperature 225 feet above on the slope was only 51°.
Стр. 55 - ... blossoms. The thick pithy rind of the orange is a poor conductor of heat and the protection it affords causes the temperature of the interior to fall much more slowly than the temperature of the outside air. When the air temperature is falling rapidly the interior of the fruit may be as much as 7° warmer than the air surrounding it, and the temperature inside the fruit lags from an hour to an hour and a half behind the temperature of the air. As the freezing point of orange juice is about 28°...
Стр. 8 - Over this pour % pint of thin, hot starch paste and stir well. (The starch paste is made by dissolving 1 heaping tablespoonful of dry gloss starch in a little cold water, which is then added to % pint of boiling water.
Стр. 18 - ... saturated. If the temperature of saturated air be raised, it will, to the feelings, become drier, and will immediately begin to take up water which is exposed to it Air is dry or moist, not in proportion to the water it contains, but in proportion as it is more or less removed from the point of saturation. The point of saturation rises more rapidly...
Стр. 16 - Remittances should be made to the SUPERINTENDENT OF DOCUMENTS, GOVERNMENT PRINTING OFFICE, WASHINGTON, DC, by postal money order, express order, or New York draft. If currency is sent, it will be at sender's risk.
Стр. 15 - I have had ten years' experience in auditing bounty claims, and the results convince me that the system in vogue is not only ineffective, but wasteful, and, in a large measure, harmful." It is the opinion of those best informed on the subject, that the bounty system is not only vastly expensive and productive of endless fraud, but that it fails to accomplish the end desired.
