370 THE SUPPLY OF 



success. "When I left for China T gave all the seed I had thus collected 

 to an English gentleman, who, I fear, has not persevered, or I should 

 have heard something of it ; people look too much to immediate benefits. 



" If this new family is to he introduced for cross breeding, I should 

 recommend feeding them in their first and second stages on oak leaves, 

 and after that only on mulberry leaves. 



" I beg leave to conclude with my opinion, that great thanks are due 

 to Mr. Meadows for making so great an exception among the consuls in 

 China, by turning his eye and mind towards what may be advantageous 

 to the commerce and industry of the country he represents, and thereby 

 also, to the country he occupies.'' 



Mr. Major has had much experience in silkworms both in Europe 

 and China, he having beeu engaged in silk farming in the south of Italy 

 many years before he went to the East ; and his opinion, that a cross 

 between the Newchang worm and that of China and Europe might be 

 effected with advantage, is, therefore, worth consideration. Kang-ni, 

 the second Emperor of the reigning dynasty, appears to have made the 

 first experiment of feeding silkworms on oak leaves about 200 years 

 ago ; and specimens of the cocoon obtained are to be seen in the Mu- 

 seum of the Chamber of Commerce at Lyons at the present day, having 

 been sent home by the Jesuit missionaries who, under that Emperor, 

 gained so prominent a position in China. It is evident, from Mr. 

 Meadows' report, that since then the worm has thriven and multiplied. 



THE SUPPLY OF TURPENTINE AND RESIN. 



BY THE EDITOR. 



In a former volume (vol. ii., p. 209) we gave some information as to the 



modus operandi pursued for obtaining turpentine in the Southern States 



of America. The supply from that quarter has been cut off, owing to 



the protracted civil war ; and the Secretary of State for the Colonies, at 



the instigation of the Board of Trade, has drawn the attention of the 



colonial governors to the subject, in order that persons who are in a 



favourable position for furnishing a supply of these articles may have 



the facts before them. Canada, Vancouver, and New Zealand might do 



something in this matter. At present, France, Greece, and Turkey are 



deriving benefits from the demand for these products, the market price 



for which has doubled in the last three years. 



The decreasing supplies are shown in the following figures : —
