of food has been injurious, it was on account of the animal eating 

 too much and thus cloying the stomach. We know a practical 

 farmer who frequently fats his beef, and hogs, upon nothing but 

 apples, and has ever found it a palatable and nourishing species of 

 food. VV^e hope to have a communication from him on this subject. 



EXTRAORDINARY YIELD. 



The River La Plate or long red Potato, is noted for its fruit- 

 fulness. A gentleman of this town, raised the present season from 

 two bushels and a peck, fifty bushels. The ground was broken up 

 last year, planted with potatoes and manured very liberally. The 

 present year it was not manured at all — the potatoes were cut into 

 one or two pieces — one piece was planted in a hill and the eyes 

 were carefully placed uppermost. They were hoed as soon as 

 they were up, and also after they were about six inches high. 



Another person informs us, that he once raised over three pecks 

 from one potato of this kind. 



IVEISCELLANEOUS. 



Diseate of Silk Worms, and its cure. 

 In the southern parts of France, where silk worms are raised, it 

 is very common to observe the insects attacked by a disease called 

 the jaundice, in consequence of the color acquired by them. Very 

 careful examination is continually made for the discovery of such 

 worms as may be attacked by it, that they may be removed, lest 

 the disease, being contagious, should spread to the others. 



The Abbe Eysseric of Carpentras, had recourse to a remedy in 

 these cases, which, though apparently dangerous, had been war- 

 ranted by the success of twenty years. He used to powder his 

 worms over with quick-lime by means of a silk sieve ; he then gave 

 them mulberry leaves moistened with a [ew drops of wine, and the 

 insects instantly set about devouring the leaves with an eagerness 

 which they did not usually show. Not one of the hurdles upon 

 which he raised his worms, appeared infected wilh the jaundice. 

 It was at first supposed, that the cocoons of silk were injured bj 

 this process ; this, however, is not the case, and his method of 

 practice is now adopted generally in the department of Vaucluse.
