cements from burnt lime and alabaster, and therefore do not give a further insight into 

 the gradual growth of the Bussian cement production. The gradual increase of tlie 

 output of Portland cement may be seen from the example of the most striking 

 centres of its manufacture, the Eiga and Novorossisk works. 



The figures in the following table are taken from the accounts of the works, 

 showing the production of the Eiga cement factories.

The output of Portland cement from the Novorossisk Cement Works; 



The production of Eoman cement is carried on at certain of the above men- 

 tioned factories, and besides the three special Eoman cement works beforemenlioned, 

 at several other partially rural industries. Thus in 1801, the station of Podolsk on 

 the Moscow-Kursk Eailway dispatched 3,417 cars of Eoman cement, 1,759 of 

 which were from the Podolsk cement works of the Moscow Joint-Stock Company, and 

 the remainder from eight other small works in the neighbourhood of Moscow. The 

 production of Eoman cement varies according to the market, to a somewhat considerable 

 extent, as is seen from the preceding table on the output of the Eiga works; 

 and its relative yearly amount can only be given approximately at 300 to 450 thous- 

 and barrels for all the factories together. 



Such a production as ten million pouds of Portland cement per annum is natur- 

 ally small in comparison to that of those countries which have an export cement 

 trade, such as Germany. The German production of Portland cement, which was 

 established towards the middle of the sixties, increased with unwonted rapidity, and in 

 1878 reached to more than 2,500,000 barrels, or twice as much as the present Eussian 

 output; in 1886 the 48 works forming the «Union of the German Cement Works»
