Tlie importation of goods analogous ti) cement cannot in general jiresent 

 figures progressively increasing or decreasing witli the course of years; therefore, it is 

 very difficult to give a representation of tlie development of the internal |))'oduction of 

 the country to which this importation was directed. Tlie independent Russian in- 

 dustry could only admit, in the calculations for its future growth, that amount of the 

 demand for cement which could be regarded as the true average for several years ; 

 moreover, the character of the building season varies every year, and therefore the 

 demand for cement is subject to considerable fluctuations, depending upon the varia- 

 tions of the work during the building season. In cases of an unexpected increase in 

 the demand at a certain mouient, the importation of foreign cement may appear in 

 the quality of a balance for the Russian markets. And these somewhat sharp and 

 accidental fluctuations reflect themselves on the figures of the imports, notwitlistand- 

 ing the successive growth of the internal Russian production. The preceding table 

 gives the amount of the importation of cement, and almost exclusively of Portland 

 cement, into Russia from 1872. Up to 1882 the statistics of the imports include 

 lime, after which the cements are put separately from other building materials. 



The total annual consumption of cements in Russia thus amounts to 14 million 

 pouds of home manufacture, and taking the average for the last 7 years, about one and 

 one-half million pouds of imported cement, altogether to the sum of nearly 7 million 

 roubles paper. 



The quality of the Russian Portland cement has long been recognized as equal 

 to that of the best foreign makes, such as the English and the German. This can be 

 stated now with firm conviction, since the testing and reception of the cement 

 for Government works and private builders, has acquired its present state of per-
