There is no doubt but that inferior kinds of water produce derangement of the digestive organs, and subsequently loss of flesh, debility, &c. We have frequently made _post mortem_ examinations of animals that have died from disease induced by debility, and have often found a large number of worms in the stomach and intestines, which, we firmly believe, had their origin either primarily from the water itself, or subsequently from its effects on the digestive function. All decayed animal and vegetable matter tends to corrupt water, and render it unfit for the purposes of life. Now, if the farmer has the best spring in the world, and the water shall flow from it, as it sometimes does, through whole fields of gutter or dike, abounding in decayed filth, such water will be impregnated with agents that will more or less affect its purity. REMARKS ON FEEDING CATTLE. Many of the most complicated diseases of cattle originate from the food: for example, it may be given in too large quantities--more than is needed to build up and repair the waste that is constantly going on. The consequence is, the animals get into a state of plethora, which is known by heaviness, dulness, unwillingness to move; there is a disposition to sleep, and they will lie down and often go to sleep in damp places. A chill of the extremities, or collapse of the capillaries, takes place, resulting in diseases of the lungs and pleura. At other times, if driven a short distance, and made to walk fast, they are liable to disease of the brain and other organs, which frequently terminates fatally. The food may be of such a nature as shall be very difficult of digestion, such as cornstalks, foxgrass, frosted turnips, &c. The clover and grasses may abound in woody fibre, in consequence of being cut too late; they will then require more than the usual amount of gastric fluids to insalivate them, and more time to masticate, and, finally, extract their nutrimental properties. The stomach becomes overworked, producing sympathetic diseases of the brain and nervous structures. The stomach not being able to act on fibrous matter with the same despatch as on softer materials, the former accumulates in its different compartments, distends the viscera, interferes with the motion of the diaphragm, presses on the liver, seriously interfering with the bile-secreting process. In order to prevent the grass and clover from becoming tough and fibrous, it should be mowed early, and while in flower, and should be afterwards almost constantly attended to, if the weather is favorable; the more it is scattered about, the better will it be made, and the more effectually will its fragrance and other good qualities be preserved.
