Vol. IX. FEBRUARY, 1912. No. 2. 



The Agricultural Xews (West Indies) for November 25 con- 

 tains a leading article of two pages on "The A^ssimilation of 

 Nitrogen by Rice,'' which consists mainly of a review of Bulletin 

 No. 24 of the Hawaii Agricultural Experiment Station. 



A machine for separating and straining lime juice, which costs 

 only $100 and has a capacity of 300 gallons an hour — equivalent 

 to about forty barrels of limes — has been proved successful at the 

 botanic station, Dominica. It is surprising that the growing of 

 limes, on a commercial basis, is greatly neglected in Hawaii 

 where the demand for the fresh fruit is generally ahead of the 

 supply. Both limes and lime juice ought to be articles of pro- 

 fitable export from these islands. 



THE COTTON WORM. 



Hawaii was not singular the past year in receiving an invasion 

 of the cotton boll worm, although coming in the nascent period 

 of the revived industry — after suspension of enterprise in that 

 product for more than a generation's lifetime — the blow fell with 

 peculiar force here. A letter to the Imperial department of agri- 

 culture, West Indies, from W. D. Hunter, in charge of the south- 

 ern field crop insect investigations of the bureau of entomology 

 of the United States department of agriculture, stated that a most 

 extraordinary outbreak of the cotton worm {Alabama argillacca) 

 had been experienced in the United States during the past cotton- 

 growing season, the cotton fields from Texas to the Atlantic 

 having been completely defoliated. Mr. Hunter was endeavoring 

 to ascertain the sources from which the enormous numbers of 

 these moths had come. He believed that in one case they 

 migrated into the United States along the Mexican coast, and he 

 raised the question as to whether another migration might not 

 have taken place from the West Indies. In answer to this sug- 

 gestion the Agricultural News says, "It does not seem likely that 

 the West Indies could have furnished any large number of cotton 

 moths during the past two or three seasons, as this insect has not 

 been very abundant, in the Lesser Antilles at least." From 

 articles in American periodicals the News tells of the capture of 

 a number of moths of the cotton worm at A^mherst, Mass., and 

 the appearance of myriads of them in Philadelphia, on which Dr. 

 Henry Skinner is quoted as saying: ''There were many thou-
