A cigarette weighing 27 grains will give 8.5 grains of ash, of which 

 1.75 grains is potash ; 



A pipe holding 25.5 grains of tobacco will give 8 grains of ash with 

 1.6 grains of potash. 



The results of systematic collecting of tobacco ash and unburnt tobacco 

 also show that tobacco ash and unburnt tobacco from : 



i) the smoke-room of a club, collected for eight days, weighed 9^/4 

 ounces. 



2) the lounge of a large hotel, collected for four days, weighed 13 

 ounces. 



3) a large restaurant, collected for 10 days, weighed 2 lbs. 8 ozs. 



4) a music hall,, one tenth part of the auditorium, one performance 

 only, weighed 4 ounces. 



The tobacco consumed in the United Kingdom during the financial 

 x'-ear 1913-1914 was 98,412,412 lbs.; the cigars imported weighed 1,331,802 

 lbs. This would give a total consumption of 44,529 tons, which would 

 represent 13,359 "tons of ash. Reckoning the latter quantit}^ as kainit 

 with 12.5 per cent, of potash, it would represent 21,376 tons of kainite worth 

 nearly £ 51,000. In the spring of 1915 it was worth nearly three times as 

 much.

I. — The production of sulphate of ammonia in Southern Russia, where 

 this industry is almost entireh^ concentrated, has during the last few 3-ear3 

 increased parallel with the development of the coke industry in the basin of 

 the Donetz : 



In 1911, the production was 491 metric tons 



In 1912 " " " 4013 "■ " 



In 1913 " " " 13 808 " " 



In 1914 " " " 17 176 " " 



In 1915, this production reached 16 3S0 metric tons, and stocks at 

 the end of the year amounted to 24 570 tons. It is anticipated that the 

 production for this year will be 32 760 tons, so that this year Russia will 

 have at its disposal about 57 330 tons of sulphate of ammonia (24 570 tons 

 in stock and 32 760 tons manufactured in 191 6). 



Before the present war, almost the whole of the sulphate of ammonia was 

 exported. It high price precluded its use as a fertiliser in Russia. Exporta- 

 tion ha\nng been stopped by the war, the price dropped to 29 francs per 

 quintal (220 lbs). Importation of nitrate of soda being also suspended, Rus-
