insects and /examples of their destructive work. The 

 method of determining the strength of commercial tim- 

 bers is shown by a testing machine, while the results of 

 tests are shown by charts and tested timbers. There is 

 also a large collection of timbers, both from the United 

 States and Europe, treated by different preservative proc- 

 esses to show the manner of increasing the life of various 

 construction timbers. Several specimens are shown of 

 building and other timbers which have been in use for 

 thirty jears or more. 



One of the special features of the exhibit is a re- 

 lief map of the United States cast upon a section of a 

 sphere sixteen feet in diameter. By using this type .of 

 map the geographical distortion inevitable in flat maps 

 is avoided, and the real relationship of the various parts 

 of the country and their actual position on the globe are 

 correctly shown. The distribution and character of the 

 forests of the country are shown in different colors, as 

 are the location and extent of National and State forest 

 reserves. The forests managed according to working 

 plans prepared by the. Bureau and lands upon which 

 plantations have been instituted under Bureau planting 

 plans are also indicated by special symbols. The situa- 

 tion of forest schools and other institutions which afford 

 training in forestry is shown on the map. On another 

 relief map are shown the location of the proposed Appa- 

 lachian Forest Reserve, the extent and character of forest 

 and other lands included, and the relation of the reserve 

 to the surrounding country. 



THE FUTURE OF SALT LAKE. 



No other city of the West can, with resonable 

 assurance, look forward to the developments of the 

 next five years with as great confidence as does Salt 

 Lake. 



The center of a region of mineral wealth, the mines 

 of which have already paid more than $70,000,000 in 

 dividends, and which even yet is comparatively unde- 

 veloped, Salt Lake is fast becoming one of the great- 

 est of smelting centers and is now taxed to find facil- 

 ities for handling the constantly increasing mineral 

 production. 



The vast irrigation enterprises now under way by 

 the United States Government will reclaim a great em- 

 pire of Utah's arid land, adding to the already rich 

 agricultural and horticultural resources of the State 

 and will afford opportunities for tens of thousands to 

 secure good homes in the region tributary to Salt Lake. 



The certainty of three new railroads will make 

 Salt Lake the railroad center of the West and draw 

 to it the wealth and trade from a vast extent of nat- 

 urally rich and hitherto undeveloped country. The 

 roads centering in the city are spending millions in 

 the improvement of terminal facilities and depots, and 

 at the same time constantly bettering their trackage and 

 equipment. 



Salt Lake has gained steadily in population during 

 the past five years, has now upwards of 80,000 inhabi- 

 tants, and according to the constantly increasing ratio 

 of growth will pass the 100,000 mark before the pres- 

 ent decade passes. 



Salt Lake is primarily a city of homes. The hun- 

 dreds of new houses that have been erected annually 

 during the last three years have in the great majority 

 of cases been for owner, not tenant, and it is certain 

 that this year's Irailding record will pass the $2,000,000 

 mark set by 1903. 



For attractiveness, both in winter and summer, the 

 city is admittedly unsurpassed in climate ; its school sys- 

 tem is the best and most modern in the West, its home 

 resources are more varied and extensive and it offers 

 the best opportunity for the wage earner who seeks a 

 home, for the business man who wants a location, for 

 the capitalist who is looking for profitable investment.
