Описание: Excerpt from Canada Department of Agriculture, Central Experimental Farm, Report of the Entomologist and Botanist, 1904 Potatoes were in most districts a satisfactory cr0p. The Colorado Potato Beetle was less aggressive than for many years, and no new enemies of prime importance were reported. The Potato Aphis occurred at Mahone Bay, in Nova Scotia, and did some harm but this is an insect which so far has only appeared at long intervals. The Potato Rot has been rather prevalent and destructive. In Prince Edward Island 'the root crops were good - potatoes never better nor less attacked by pests of any kind.' (rev. A. E. Burke.) At the Provincial Exhibition held at Charlottetown in September last, the exhibit of potatoes was simply wonderful, the tubers being even in size and remarkably free of blemish. In Nova Scotia the crop was a good average one, with little mention of rot. In Ontario there was a large yield, but considerable rot appeared, especially on heavy soil or on low land; the extent of the loss is var iously estimated at from 20 to 50 per cent. In British Columbia, Mr. J. R. Anderson says: 'potatoes are decidedly under the average in those sections where the best qualities are produced; fair on low lands; prices firm. The yield of other root crops is about normal, but short in some of the higher regions, although the quality is good? Spraying potato fields with Bordeaux mixture to prevent injury by the Potato Bot has again shown the great value of this useful remedy. Four sprayings on August 1, 15, 31 and September 14, gave potatoes absolutely free of all traces of disease This was on light sandy land, and, as a rule, one or two more sprayings would be advisable. The saving from this treatment for Potato Rot is now so well established and so many object lessons have been given at fall exhibitions and on the experimental farms, that it is a most remarkable thing that more farmers and others do not practise such a simple method of saving a large proportion of their crop. Although, as with every other remedy, there is a variation in the amount of protection, in every instance that has come under my notice, and these have been many since we began to spray potatoes on the experimental farms, to show farmers what an excellent remedy it is - it has been invariably shown that spraying potatoes with the Bordeaux mixture to prevent Potato Rot always pays. Every year such demonstration plots have been grown since 1891, and, besides this, the Horticulturist and Agriculturist now spray all their potatoes as an economic method of obtaining as big a crop as possible.

Описание: Excerpt from Diseases and Parasites of Poultry Symptoms - There are no prominent symptoms by which the disease can be dis nosed during life, and it is only by the examination of the internal organs after dea that the trouble is recognized. The disease runs a chronic course, and birds do n show signs of illness until just before death, when the pathological changes are so far a mood as to preclude medicinal treatment. These changes are to be observed in t'. Liver and caeca. The cacea are two elongated blind pouches at the lower end of t' small intestines. In the normal fowl they are of uniform diameter throughout, t walls thin and the mucus membrane pale; they are filled with a rather dry, greeui excrement In entero-hepatitis one or both caeca have their walls greatly thickens either throughout or in spots. The mucus membrane is deeply reddened and erode and from this inflamed surface there is poured into the caeca a quantity of cross material or exudate more or less tinted with blood. The liver also shows marked a terations. It is enlarged and darkened, due to engorgement with blood, and scatter over its surface are round spots, sometimes whitish or again with yellowish tint These spots are so distinct that no one can fail to mognize them. Prevention - Isolation of the sick and disinfection of the houses occupied by t healthy. Particularly is it important to guard the young birds which are more at ceptible to the contagion. It will therefore be best where the disease has been prey lent to remove the young to new quarters, where the trouble has never before existAbout the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
