Paris, who had performed many experiments to prove 

 that this branch of industry can be successfully carried 

 on through all the northern departments of France. He 

 also had ascertained, by experiments at Paris, that the 

 cocoons which were produced by silkworms fed exclu- 

 sively on the Morus multicaulis, were even rather heavier 

 than other cocoons. The more complete and effectual 

 conversion of Dr. Pascalis to the system, does not ap- 

 pear so fully until afterwards, when speaking of the M. 

 multicaulis, which he had received from France, he 

 avers, that, " after the discovery of this plant, a doubt 

 no longer exists, that two crops of silks may be produced 

 in a single season." 



SECTION XLIII. 



MODERN SYSTEM OF COUNT DANDOLO, OF ITALY, 

 AND OF FRANCE. 



THE specimen house of Mons. Matthiew Bonafoux, 

 of Piedmont, the disciple of Count Dandolo, though 

 calculated for 160,000, yet in this instance it contained 

 but 80,000. The house is isolated and exposed on all 

 sides. It is by the side of a brook. It is twenty feet 

 square in the clear, of course the same in height. 

 Around the four walls, at ten feet from the floor, there 

 runs a frame gallery, which facilitates the attendance of 

 the nursery in all its parts. There are five windows 

 and thirteen ventilators through the walls, so disposed 

 as to admit fresh air on all sides. These last are a foot 

 square, more or less, and furnished with slides ; and 

 seven ventilators in the roof to open with cords. There 

 are two stoves in opposite angles, each with an air 

 chamber for heated air ; also a fire place in the side 

 with a broad hearth, for fires of light blaze, or flame 

 fires. There are forty hurdles, each fifteen feet long 

 and three feet wide, sufficient for four ounces. Oppo-
