P'owu ill Viioiniii agreed very well in their asli conieiit excei)t in one 

 county, where it was much lower. The potash did not agree except in 

 1 or 2 cases. The lime content varied considerably in all cases, and in 

 chlorin and in insoluble matter there was very little agreement. The 

 shipping tobaccos from the Virginia Department of Agriculture c(m- 

 tained ab;)ut ^ more potash, about :\ less lime, and about 4 times as 

 mnch cldorin as the other. 



In the samples from West Virginia and North Caiolina the ash con- 

 stituents agreed fairly well; the chlorin varied considerably, ranging 

 in the ash from 2.22 to 8.08 per cent. The percentage of ash, nitrogen, 

 and potasli was higher and that of lime nuich lower in the samples 

 from West Virginia than in those from North Carolina. 



Percencage of nicotin in tobacco, R. -T. Davidson ( Virfjlnia Sta. 

 linl. 52^ pp. 1)7-72). — The percentage of nicotin is given for 3 varieties 

 of tobacco at 5 stages of growth — in the plant bed, at topping, at cut- 

 ting, partly cured, and cured; also in 21 samples of different grades of 

 manufacturing tobacco grown in different counties of Virginia, West 

 Virginia, ami North Carolina, including in some cases the crops of 

 different years. The data are tabulated. 



Comparing the varieties Burley, Prior, and Oronoko, ''we see that in 

 the case of the plant taken from the plant bed there is very little differ- 

 ence [in the nicotin content]. At time of top])ing, in case of the leaf, the 

 agreement is very close. ... In the stalk the agreement is not so 

 close, the Burley containing about twice as much as the Prior, and 

 nearly three times as much as the Oronoko. In the root the difference 

 is very slight. ... At time of cutting the leaf does not show the 

 same agreement e\cei)t in case of the Pryor and Oronoko, when it 

 agrees fairly well, the Burley being lowest, over 0.5 per cent less than 

 the Oronoko and over 1 per cent less than the Prior. The percentages 

 in the stalk agree much better at this time, being very nearly the same 

 in the 3 varieties.'' 



Among the different grades of manufacturing tobacco the author 

 states that the light tobacco contained the lowest and the dark the 

 highest percentage of nicotin; it ranged from 1.54: in high-grade bright 

 tiue cured to 5.5G in English shipping. 



A comparison of phosphatic slag and nitrate of soda \vith 

 ground bone on oats and corn, C. A. (Ioessmann {M((ss(ichusctfs 

 Hatch St((. Rpt. /iS'.'AJ, pp. 308-310). — This is a continuation of work pub- 

 lished in the Annual Ileport of the State iStaticui for 1894 (E. 8. K., 7, p. 

 291). Two plats were used, 1 and 1.8 acres in extent. One received line 

 ground bone, the other phosphatic slag, and both muriate of potash.
