I received from Mens. Guerin" Meneville, in the name of the 

 society, forty eggs of it laid partly on the 19th, 20th and 21st of 

 August. These were kept at the natural temperature of IS'^to 

 20° Centigrade, 65° to 67° Fahrenheit, hatched from the first to 

 the fourth of September. Two of them perished and gave no 

 worms. Care of those first hatched at same temperature, fed 

 with shoots of trimmed oak; these kept in bottles of water. But 

 it is well understood that this silkworm requires raising in open 

 air and will not flourish under cover. 



TOKAY WINE. 



Some years of cultiv^ation of the Tokay vines from Hungary, 

 proves its successful introduction into France. 



NEW SILK W^ORM. 



Modem silk seems to have suffered injury by degeneracy of the 

 worm fed on the morus mulberry. 



We have received a Chinese silk worm, the Saturnia Mylittay 

 which lives on the oak. 



Mons. Guerin Meneville has caused the experiment to be tried 

 in-doors, by feeding the new worm on young oak leaves, placing 

 small branches of young oak shoots in bottles of water for the 

 worms to feed on in rooms as with the morus. But it seems ihat 

 this new worm will do best in open air. 



The Saiurnia Cynthia can be raised under cover like the com- 

 mon mulberry silk worms. It may be raised on the leaves of 

 castor oil nut plant.

THE NEW IGNAME OF NEW ZEALAND. 



This Yam, or Dioscorea Batata, has been found to weigh "from 

 10 to 40 pounds in growing from February to last of October. 

 This tuber is egg shaped and singular in being at the smaller end 

 smooth with thin skin, and coarse with thick skin at the top. In 

 France it has attained the weight of five pounds. 



THE SUGAR SORGHO. 



Hardy says that most of the stalks grew from 13 to 17 feet 

 high. Seed ripe in middle of September, gave about a thousand 

 pounds weight of seed per acre. The weight of the sugary por- 

 tion of the stalks was about forty tons weight per acre. 



The stalks being chopped up and subjected to heavy pressure, 

 gave 67 per cent of juice, which had the density of 8° | Baume, 

 which approximates to 13 per cent of sugar. Supposing that all 

 the sugar in it is crystalizable, we should then obtain from an
