should consult mill engineers for estimates and details of equipment and erection. 

 These engineers advertise in the technical journals, especially in the paper-trade 

 journals, and their names may be found in the directories of many of the larger cities. 

 It may be said, however, that estimates for the erection and equipping of paper 

 mills, exclusive of water-power rights and wood rights, vary from $10,000 to $25,000 

 per day cord. From $500 to $2,000 should be added to these figures to cover the 

 additional equipment required for the utilization of by-products, if the wood is 

 cooked at once with caustic soda, and from $1,000 to $3,000 should be added if the 

 resins are first extracted with a volatile solvent and turpentine and rosin made instead 

 of turpentine and rosin oils. It is the opinion in this bureau that costs of erecting 

 and equipping approximate the lower rather than the higher figures.
