sugar per acre, but sometimes runs as high as 14: tons. The cost of 

 production varies from $22.50 to ^-i-i per ton of sugar in the data 

 given, and will average 135 or more. The profit per ton of sugar 

 varies from $25 to $35. 



Conditions that will tend to increase the cost of production are the 

 probable higher wages that will have to be paid for lal)or when pres- 

 ent contracts with Chinese and Japanese laborers expire. The annexa- 

 tion of the islands to the United States wall prevent the emigration of 

 Chinese to the islands and prohibit the importation of contract laljor 

 from other countries. 



Statistics regarding public lands in the islands, sugar factories, 

 imports and exports, lal)or, and wages are given, with descriptions of 

 all the principal sugar plantations and factories in operation in the 

 islands. 



Re])ort of the chemist, 11. W. 117% (pp. 136-193).— In 1898, 12,110 

 lbs. of sugar-beet seed was distril)uted by the Division of Botan}" of 

 this Department, nearly one-half going to 29 of the experiment sta- 

 tions, and the remainder to individuals and associations. In 1899, 96-1 

 samples of beets from 41 States and Territories were received, and the 

 data secured in their analysis bv the Division of Chemistr}^ are shown 

 in tables and summarized for 3 j^ears. From the data at hand the 

 adaptation of the different States foi' sugar production is summed up 

 as follow^s: Beet sugar can be produced profitably in California, Colo- 

 rado, Michigan, Nebraska, Nevada, New York, Pennsylvania, Utah, 

 Wisconsin, and Wyoming. It can not be produced with profit in Arkan- 

 sas, District of Columbia, Georgia, Kansas, Kentucky, North Carolina, 

 Oklahoma, South Carolina, and Tennessee. It may possibl}- be pro- 

 duced at a profit in Connecticut, Delaware, Idaho, Illinois, Indiana, 

 Iowa, Maryland, Massachusetts, Minnesota, Missouri, Montana, New 

 Hampshire, New Jersey, New Mexico, North Dakota, Ohio, Oregon, 

 South Dakota, Vermont, Virginia, and Washington. 



The methods employed by factories in Michigan for determining the 

 deductions to be made for tare, the analysis of beets, etc., are given 

 in detail. 



Investigation of Svimatra tobacco, A. Van Bijlert {Meded. ^ S. 

 Lands Plantentuin, 1899, No. 30, jjp. 156). — The author gives au 

 account of work done on texture and chemical composition of 15 

 samples of unfermented Sumatra tobacco. Since this tobacco is used 

 exclusively for cigar wrappers, the flavor and fragrance received no 

 attention, but the weight, clasticit}-, burning quality, white ash, 

 amount of leaf surface, together with color, spotting, etc., were care- 

 fully noted. 



The relation between weight and the extent of leaf surface is given, 

 the different measurements and weights being tabulated. From this it 

 appears that there is no constant relation between the character of the
