FIELD CROPS. 839 



In another experiment oiie-sixtii of ;ni ;i<n> \v;is uiuler shelter. The land, 

 which had had no cover crup duriii;;; the iirecodin;:; winter, was thoronglily 

 cultivated early in spring and iertilized just before planting with 500 lbs. of 

 commercial fertilizer rich in organic nitrogen, suli)hate of potash, and acidu- 

 lated bone. The tobaceo was planted June !) and 14, cultivated .July 20, hoed 

 July 1, 14, 10, L'S and oO, and topped and suckored on July 27 and August 11 

 and 13. The leaf was ready for priming September 1, 2, 7, 12, 17 and 10 and 

 the harvesting was finished September 21. The curing was done in the same 

 manner and as satisfactorily as in the previously described work, and the 

 tobacco was taken down December 27 and 28 and sorted for sweating. The 

 temperatures during the bulk sweating and the dates on which the bulks were 

 turned are given. At no time during the process of fermentation was the tem- 

 perature allowed to go over 112° F. The sizing and the sorting of the crop was 

 begun on February 15. The total weight of leaf submitted for sweating was 

 418 lbs. and the weight after sorting and finishing sweating 400 lbs. 



In the Marietta crops of 1002 and lOOo. 43 and 41 per cent respectively was 

 second-quality leaf, while the first experiment here described showe<l but 22 per 

 cent and the second about 35 per cent of this grade. The luster of the two 

 crops of 1004 was little, if at all, inferior to that of the average imported Su- 

 matra wrapiier u.sed in the Lancaster County cigar factories, but it was not so 

 good as that of the best Sumatra wrapper. In the first experiment the yield 

 was at the rate of 008 lbs. per acre, of which 708 lbs. were of tirst-iiuality 

 wrapper. It is estimated that the cost of the leaf produced in these experiments 

 ranged from 02 to 07 cts. per pound. 



The experiments here reported are considered as indicating in general the 

 possibility of growing from seed of the Sumatra strain under shelter on the 

 light, sandy type of soil in northern Lancaster County a wrapper leaf approach- 

 ing in quality the average imported Sumatra with respect to color, luster, fine- 

 ness of vein, wrapping capacity and burn. It is further stated that the yield 

 per acre in relation to the cost of production and the selling price of the leaf 

 is sufficiently large to make shade culture protitaiile, but attention is called to 

 the fact that since the results are of but u single season's test they do not 

 afford a safe basis of judgment with resitect to yield ami (luality during an 

 average season in that locality. 



The tobacco industry in the United States, M. Jacobstein {Columbia Univ. 

 IStudics Polit. Sci., 2U {I'JOl), Xa. 3, mi. ^OS). — This work gives a historical 

 survey of the tobacco industry, including the colonial period and the period 

 from 1776-1860. The time from 1860-1005 is considered the modern period of 

 the industry and under this heading are discussed consumption, cultivation, 

 manufacture, the tobacco trust, labor conditions in the tobacco industry, foreign 

 trade, and the tobacco tax. 



Tobacco ash (MaJcd. DcU-1'rorfstat. Mrclan, J (1907), No. U, pp. 192-20^).— 

 The chemical conu)osition of tobacco ash was studied with a view to determin- 

 ing its value for fertilizing purposes. The data secured in analyzing numerous 

 samples of ash show that in many cases when the potash content is high the 

 chlorin content is also high, ranging from 2 to 3 per cent and reducing the fer- 

 tilizer value of the ash considerably. On the other hand, a low potash content 

 was accompanied by a low chlorin content, and such samples are regarded as 

 having a good fertilizer value. A high potash content and a low chlorin con- 

 tent were very seldom foinid in the same sample. In 00 i)er cent of the samples 

 analyzed the relation of potash to chlorin was as 10 to 20, and in so per cent 

 as 10 to 25. It is recommended that for the i)repiiration of the ash the tobacco 

 plants be burned at a high temperature and that wood with a low chlorin 

 content be used for fuel.
