Page 79 - Among the means, which have been employed to this end, none have been attended with greater success than the establishment of boards, composed of proper characters, charged with collecting and diffusing information, and enabled by premiums, and small pecuniary aids, to encourage and assist a spirit of discovery and improvement.
Page 183 - ... important that we should maintain the high level of our present prosperity. We have now reached the point in the development of our interests where we are not only able to supply our own markets but to produce a constantly growing surplus for which we must find markets abroad. To secure these markets we can utilize existing duties in any case where they are no longer needed for the purpose of protection...
Page 63 - Water, ,r>0 gallons. The standard remedy for the destruction of insects which eat the foliage or fruit. The lime is added to prevent the Paris green from burning the foliage. Slack the lime in a little water, make into a thin paste. Mix the lime and Paris green and add the remainder of the water.
Page 79 - ... charged with collecting and diffusing information, and enabled by premiums and small pecuniary aids to encourage and assist a spirit of discovery and improvement. This species of establishment contributes doubly to the increase of improvement by stimulating to enterprise and experiment, and by drawing to a common center the results everywhere of individual skill and observation, and spreading them thence over the whole nation.

Page 61 - It sometimes happens, therefore, that farmers are led to believe that their potatoes are affected with early blight and other diseases when the trouble has been brought on by themselves through the improper use of Paris green.

Page 58 - Another test is to place a little of the Paris green between two pieces of window glass and rub them together. If the Paris green is adulterated with lime, barium sulphate, or similar white materials, the Paris green will appear to turn white in places. Paris green of good quality is intensely bright green and uniform. When adulterated, the green loses something of its intensity and is grayish green and is not always uniform.
Page 60 - ... swept by fire. The rapid spread of the disease, which is caused by a parasitic fungus, is dependent in large measure upon certain conditions of moisture and heat. A daily mean or normal temperature of from 72 to 74 F. for any considerable time, accompanied by moist weather, furnishes the best conditions for the spread of the parasite. On the other hand, if the daily mean or normal temperature exceeds 77 for a few days, the development of the disease is checked.
Page 172 - The reason for this is simple ; one has to drink a large quantity to get the needed nourishment, and further it is so readily disposed of that it does not satisfy the sense of hunger. But when eaten with bread, or used in cooking, it is a food material the value of which is not at all appreciated by the farmer. A pound of lean beef contains about .180 pounds of flesh formers, and has a fuel value of 870 calories.
Page 63 - Arsenate 1 pound Water 50 gallons Arsenate of Lead acts slower as a poison than Paris green. It can be kept suspended in the water better than Paris green ; it does not burn foliage and sticks to the foliage better than Paris green.
Page 63 - Slake the lime by the addition of a small amount of water, and when slaked add 2 or 3 gallons of water and stir freely. Pour the milk of lime thus made into the sulphate solution, passing it through a brass wire strainer of about 30 meshes to the inch (No. 50), or through...
