Partial averages. TO be compared only 



At present a very large proportion of American cement is marketed 

 in sacks or bags, packing in wood being almost entirely confined to 

 cement intended for export or coastwise shipment. Foreign cement, of 

 course, reaches the American market in barrels, but imported cements 

 .are becoming of less consequence each year. 



When cement is packed in wood, the barrels are usually charged for 

 at a rate sufficient to give a slight profit to the packing department of 

 the mill. Bags and sacks are also charged extra, with a rebate for re- 

 turned bags. In figuring the cost of cement manufacture it is there- 

 fore unnecessary to include the actual cost of the packages, but the 

 labor and power used in the packing-house must be figured in.
