this, prices were on about the same level as in 1906. The con- 

 ditions in the natural rock cement trade have been less favor- 

 able than in the other branch, reflecting influences which are of 

 general nature and have been operative for some time. 



There are 10 counties in the State which manufacture hydraulic 

 cement. The crude materials used are found in nearly every 

 section and the development of the industry has been governed 

 more by commercial considerations, such as fuel prices and 

 facilities ior shipment of the product to market, than by the 

 distribution of natural resources. Over one half of the annual 

 production of the State is made in the Hudson river region and 

 most of the remainder in the central and western part along the 

 main trunk lines and the Erie canal. Ulster county has long 

 been the center of the natural rock cement industry, while Onon- 

 daga and Erie counties furnish smaller quantities of the material. 

 The Portland cement plants are located in Columbia, Greene, 

 Livingston, Onondaga, Schoharie, Steuben, Tompkins, Ulster and 

 Warren oounties. 



For the past year there were 18 firms which reported a pro- 

 duction as compared with 19 firms so reporting in 1906. The 

 combined output of Portland and natural rock cement amounted 

 to 3,245,729 barrels valued at $2,971,820. In 1906 the output 

 was 4,114,939 barrels valued at $3,950,699, so that there was a 

 loss for the year of 869,210 barrels in quantity and of $978,879 in 

 value. The decrease was shared by both branches, but in greater 

 part by the natural rock cement. 



The production of Portland cement amounted to 2,108,450 

 barrels valued at $2,214,090, against 2,423,374 barrels valued at 

 $2,766,488 in 1906. There were 10 companies in operation dur- 

 ing the whole or a part of the year. The decrease is accounted 

 for by the fact that one of the larger plants was closed down 

 for repairs and improvements during most of the season. A 

 new plant has been erected by the William M. Hoag Cement 

 Co. at Rosendale, Ulster co., but made only experimental runs 

 in 1907. 



Of natural rock cement a production amounting to 1,137,279 

 barrels valued at $757,730 was reported, as compared with 

 1,691,565 barrels valued at $1,184,211 in the preceding year. The 

 Rosendale district contributed most of the output as hereto- 

 fore, its share having been 970,929 barrels valued at $679,650. 

 In 1906 the same district made 1,514,336 barrels valued at 

 $i»i07»535- Onondaga county reported a total of 47,350 barrels
