at intervals. The oil obtained had been pumped three or four hours 

 before it was secured by the writer. 



The following table shows the relative properties of eight samples 

 of oil from Allen and Neosho counties : 



In the above table, we would call attention to the following differ- 

 ences : The specific gravity varies from 0.866 ( Baume 32.5 ), in No. 1, 

 to 0.940 ( Baume 19.3 ), in No. 3. No. 3 and No. 5 contain some water, 

 which makes the specific gravity a trifle higher than the dry oil 

 would be. 



The flash points vary from 11" C. (52" F.), in Nos. 1, 6, and 7, to 

 143=0. (289= F.) in No. 3. 



The burning points vary from 25" C. (77° F.), in No. 1, to 72" C. 

 (360" F.), in No. 3. 



We have also made distillations of the above samples according to 

 the method of Engler. We used 300 cc. of crude oil, and carried on 

 the distillation in 500 cc. glass distilling flasks. We collected the dis- 

 tillates in five-per-cent. fractions. The results of these determina- 

 tions we will report in a later paper. 



Judging from this preliminary work, the results seem to warrant 

 the continuation of the examination of oils from other parts of the 

 Kansas field.
