of improved methods of working wood, or new applications for 

 a given wood or wood product, is at once followed by the 

 designing of apparatus which will enable the discovery to be 

 put to commercial use. 



7. Chemistry Department. — The work of this section is of 

 course carried on in close collaboration with every other section. 

 The main problems engaging its attention at present are the 

 analysis and grading of commercial creosotes to determine their 

 value as preservatives, and the analysis and grading of 

 turpentines and rosins. 



Office of Wood Utilisation, Chicago. 



The main object here, as in the Products Laboratory, is to 

 promote more economic utilisation of wood by elimination of 

 waste in both forest and mill, but, as mentioned above, this 

 Office only attempts the solution of problems which do not 

 require the application of laboratory methods and can be solved 

 by direct co-operation with lumbermen and manufacturers. 



To achieve this a thorough knowledge of the timber business 

 generally is essential, and detailed studies are being made of the 

 wood-using industries of each State. These studies include 

 statistics of production and consumption of lumber, the kinds 

 of wood used, the source whence obtained, the product manu- 

 factured from each kind, and a variety of information as to 

 market conditions, prices, etc. The work is carried on in 

 co-operation with manufacturers, who are invited to supply the 

 necessary information, and in most cases the States also lend 

 the assistance of their Boards of Forestry, of Agriculture, of 

 Labour, of Statistics, etc. 



As a result of the knowledge acquired by these studies, 

 covering as they do every important home wood-using industry, 

 the Office is enabled to co-operate still more closely with 

 manufacturers by giving valuable suggestions for the utilisation 

 of material which would otherwise be regarded as waste. The 

 Office is also ready to help manufacturers in the discovery 

 of substitutes for species of trees which are becoming scarce. 



Forestry Schools. 



The forestry schools visited were those of Yale, Harvard, 

 Michigan and Toronto Universities, which are recognised as 

 being of the highest standard in North America. All of these
