Jatropa urens produces he says a kind of Balata very easy to 

 work and easy to propagate from seeds or cuttings. This may be so, 

 but it is not likely to be popular as a cultivated plant as it is one of 

 the worst stinging plants in the world. It is quite a small plant and 

 at Fernando de Noronha where I met with it in abundance, the 

 botanists of the Challenger expedition said the only way to gather 

 it was to lasso it with a string, haul it up and drop it in to the 

 botanical papers and drop a weight on it. It is impossible to touch 

 the plant without being stung. 



These plants, Seffer says, grow usually in ground unsuited 

 for agriculture and will give 75 pounds of rubber per acre. The 

 Plumieras are big enough to tap in three years, and the rubber can 

 be placed on the market at 2 fr. 50 per kilo at most. An English 

 Syndicate is just formed to exploit these plants with a capital of 

 7,500,000 francs. — Ed. 



SOME CORRECTIONS. 



Mr. Trelease sends the following note as to references concerning 

 the publication of the account of the Zapupe, in Bulletin No. IX. p. 569. 



THE MISSOURI BOTANICAL GARDEN. 



St. Louis, Mo., 



January 24, 1910. 



Dear Doctor Ridley, 



I am pleased to learn from the December number of the Agri- 

 cultural Bulletin that you are taking interest in the new Zapupes. 

 I notice, though, that through some inadvertence you refer to Consul 

 Millward's publication as having been contained in the Transactions 

 of our local Academy of Science. His several important practical 

 papers were actually published in our Government Consular Reports, 

 or in periodicals, while it is only my own paper on the subject (which 

 I sent you when I sent you the bulbils that you are growing) that 

 was published by the Saint Louis Academy. 



Sincerely yours, 

 Wm. TRELEASE, 

 Director. 



In the Bulletin for March, p. 84, the omission of a line in the 

 fourth paragraph makes the passage obscure, and it should read 



line 29 "nor does the suggestion that " and that thus the 



cotton is not affected after the death of the sorghum, does not seem 

 to make matters any clearer. 



P. 100 line 16, Asistic read Asiatic.
