While engaged in preparing sabinene from savin oil, we obtained a 

 fraction of b. p. 170 to 180° from which, after repeated distillation, we 

 succeeded in isolating a portion with a constant b. p.; possessing the 

 following properties: b. p. 175 to 177°, d 1B o 0,8469, « D + 0°37', n D20O 1,14137, 

 We obtained no tetrabromide, but treatment with nitric oxide yielded the 

 a-terpinene nitrosite, m. p. 156°. It follows that a-terpinene is a constituent 

 of savin oil.

Spearmint Oil. Judged by European standards of taste, it seems 

 scarcely credible that the employment of this oil in the manufacture of 

 sweets, chewing gum, 8jc, should be steadily increasing in the United 

 States. That, however, is the fact, and it is therefore due to the strong 

 demand in the country of production itself that, as already foreseen by 

 us in our last Report, the value has gradually considerably advanced. From 

 $ 2 per lb., the figure at which it stood in July 1910, the price has 

 by degrees gone up to $ 3.15, verifying our expectations of higher prices 

 which we plainly set forth in our two preceding reports. The stock now 

 left in first hand is only small. 



We can see no reason for any change in prices of this oil before 

 the 1911 crop. 



Spearmint roots always winter well, because they are imbedded so 

 deeply into the soil. 



We anticipate that there will be considerable spearmint planted this 

 spring, but even should there be, the acreage may not be increased, for 

 many of the old fields are likely to be ploughed up and used for other 

 crops. It is therefore rather difficult to forecast what prices will be when the 

 new crop is on the market. 



While preparing 1-carvone from spearmint oil by Tiemann's method, 

 F. Elze 3 ) obtained as a waste product an oil possessing a more intense 

 odour of spearmint than did the original material. This waste oil possessed 

 following constants: d 15 o 0,917, a — 28° 0'. It contained 18°/o ester (calculated 

 as dihydrocuminic acetate), and upon fractionation was split up into the 

 following parts:
