Page 462 - But as the cause of impurity may be transient, it is not easy to find experimental proof. 2. Diarrhoea or dysentery, constantly affecting a community, or returning periodically at certain times of the year, is far more likely to be produced by bad water than by any other cause. 3. A very sudden and localized outbreak of either typhoid fever or cholera, is almost certainly owing to introduction of the poison by water. 4. The same fact holds good in cases of malarious fever, and, especially if the...
Page 464 - In cases where water containing large amounts of total solid residue is necessarily used, a heavy petroleum oil, free from tar or wax, which is not acted upon by acids or alkalies, not having sufficient wax in it to cause saponification, and which has a vaporizing-point at nearly 600° F., will give the best results in preventing boiler-scale. Its action is to form a thin greasy film over the boiler linings, protecting them largely from the action of acids in the water and greasing the sediment which...
Page 462 - free ammonia " has disappeared, and nitrite has taken its place, reaching a maximum in about twenty-one days. Later the nitrite too disappears, and in twenty-eight days or more all the nitrogen has been converted into the form of nitrate. When the suspended matter is removed by filtration through paper, or by precipitation with alumina, no change occurs unless free ammonia were present at the outset.
Page 305 - Wheat of the same variety obtained from different sources and possessing widely different chemical and physical characteristics, when grown side by side in one locality yields crops which are almost the same in appearance and in composition.
Page 445 - BY CHEMICALS. By Prof. JW Ince. There has recently been submitted to this department for examination a solution of so-called "Quack Grass Destroyer." In connection with the analysis of this material, there has been collected the following data showing what has been accomplished in some of the Experiment Stations in the effort to subdue this pest by means of chemical sprays. Kerosene at the rate of 64 gallons per square rod will not kill quack grass.
Page 449 - Hilpard, in his book upon Soils, gives the following figures to show the tolerance of various plants for total alkali, the number of pounds per acre to a depth of 4 feet. Barley 25,520 Hairy Vetch 69,360 Saltbush 156,720 Sugar beet 59,840 Alfalfa, old 110,320 Salt grass 381,110 It can be readily seen, therefore, that there is enough soluble salts in the poor spots from this Edgeley field to prevent the growth of almost anything except possibly saltgrass. The only ultimate remedy for a condition like...
Page 447 - ... barrel of 44 gallons. Both of these samples came from the same source and as will be seen by the analyses have practically the same composition. As sold to the consumer for the purpose of destroying quack grass, the barrels cost six dollars. It is claimed that two barrels will destroy the weed, it there is an interval of two or three weeks between the applications. However, considering all the experiments that have been made so far, the manufacturers are not justified in making these claims....
Page 447 - Therefore, it would seem that it is not wise for farmers to buy quack grafts destroyer for at least two reasons; first, the material could be purchased for about a third of the price asked in this form; and second, the use of chemicals, (including sodium arsenite) is of doubtful efficiency for the purpose of killing quack grass. CARMINE COMPLEXION POWDER. Carmine Complexion Powder, Lab. No. 3257, is put out by the StaffordMiller Co., St. Louis, Mo. A sample of this product was examined and found...
Page 447 - No. 1232S, were taken from a circular spot of good oats which stood 28 inches high; the spot was about 12 feet in diameter, and the soil was taken from the center of the spot. Samples. Nos. 97, 98 and 99, under Lab. No. 1233S, were taken ten feet from the above sample, where the grain was only thirteen inches high. Weeds were very thick in this poor spot, while only a few were growing in the good soil. In taking the sample it was noted that in the spot where the grain was the best, the soil contained...
Page 291 - During the year a large amount of work has been done in the X-ray laboratory consisting of microscopic examinations and the taking of radiographs.
