SALIVATION OF DOMESTIC ANIMALS. 259 



juriously known among us. but the horse and the cow, and the hit- 

 ter only shglitl}. This is not true. Hogs are quite as liable to it 

 as < ows. I have seen every hog or* my farm, of all ages, amount- 

 ing to several hundreds, afflicted with it at the same time. I never 

 knew it terminate fatal'y in any animal but the horse. 



The disorder is attributed by him, to two plants or weeds, which 

 are not uncommon in this region, viz: the Euphorbia hypericifolia, 

 and the Lobelia inflata. This. 1 apprehend, is also incorrect. The 

 former weed abounds among us ; but. as he truly states, hogs do 

 not eat it ; yet (hev are more subecf to salivation than any animal 

 be-iidi' the horse. — The latter weed does not grow on my planta- 

 tion, nor in my vicinage, and yet my stock, especially my hogs, are 

 annually more or less salivated. 



This disorder is a very disagreeable one, and extremely iniurious 

 to our stock ; one which e\ery body can account for as they sup- 

 pose, yet one which all allow to be perpetuated among them. I 

 have no iheory on the subject, but I will state a few facts which \ 

 have observed for some years. 



I believe most domestic animals are subject to the disorder. 

 Horses, cows, hogs, sheep — and even my goats, I have seen sali- 

 vated. 



The condition of the animal at the time, whether fat or poor, 

 sick or well, seenfis totally immaterial — all being equally liable to 

 be attacked. 



The period of its arrival, and length of duration, are uncertain ; 

 except that it is never seen but in warm weather — and other things 

 being equal, the warmer the weather the worse the salivation. It 

 lasts from six weeks to tive months. It seems to be much more 

 violent during a dry than a wet summer. 



Stock, grazing on red clover of the first or second crop, on a re- 

 cent harvest stubble of any kind, or on an unniixed blue grass pas- 

 ture of recent formation, are not often salivated. 



On. the contrary, stock pasturing on red clover older than the 

 second crop, on an old white clover tield, or on pasture land of 

 any kind very closely bit down, are very liable to be salivated. 



The free use of water and of salt, will greatly mitigate the dis- 

 ©rdei . 



There is a very large weed found in the corners of fences, and 

 in other rich, untrodden spots, common among us, called the rich 

 or hull weed, which all stock, but especially horses, are very fond 

 of, that will mitigate the flow of saliva in a few hours, and stop it 

 in a few feeds, if the animal has not access to whatever originally 

 produced the disorder. 



The disorder may be always cured in a day or two, by feeding 

 the animals on any kind of grain whatever. I have seen a horse 

 salivated and cured several times in a week, just as his food was 

 cha!i<^ed. 



Upon the whole, 1 do not pretend to know what is the imme- 

 diate cause of the disease ; but i am satisfied that it is produced 

 by something taken into the stomach of the animal, and that it can
