o4 PRACTICAL ARBORICULTURE 
the plantation would not exceed $8,000 to $10,000. In eight years 680,000 mine 
ties and the same number of ten-foot props, possessing a value of $20,000, may be 
obtained. In eight years more a new growth from these stumps will produce an 
equal number of timbers for mines. 
In strength the catalpa far exceeds that of native timbers now used. 
SUMMARY OF RECOMMENDATIONS. 
1. Cease cutting small, immature coniferous trees; limit the size to 12 inches 
diameter. 
2. Saw railway cross-ties from large trees. 
3. Use aspen for mine timbers. 
4. Erect portable plant for chemical treatment of wood. 
5. Plant 1,000 or more acres of catalpa. 
6. Establish fire protection. 
7. Employ a forester. 
8. Leave numbers of good sound trees for seed trees. 
g. Preserve the dwarf oak and aspen for protection of coniferous seedlings. 
10. Reserve storage reservoir sites. 
11. Post printed notices warning against fire. 
12. Forbid the herding of goats. 
13. Limit the number of cattle to be herded. Confine them to treeless 
portion of grounds. 
14. Forbid sheep herding in timber. 
15. Adopt a twenty-year course of cutting timber. 
16. Select and reserve some sites for hotels and resorts. 
17. Lay the foundation for a long-time investment by perpetuating the for- 
est growths. 
18. Avoid unprofitable competition in lumber. 
IN CONCLUSION. 
A corporation of such magnitude as the Colorado Fuel and Iron Company, 
with your varied interests, landed, commercial and manufacturing, and extending 
throughout the entire Rocky Mountain region, cannot fail to be affected by what- 
ever influences the regions in which your operations are extended. 
No one thing can permanently injure this entire country to such a degree as 
a total destruction of the forests covering the higher mountains, for that changes 
the climate, water supply and future manufactures, influencing agriculture, com- 
merce and every condition of business. 
On the contrary, a conservative use of the timber which is ripe and ready 
for use, not removing all at one time, will enable nature to maintain the condi- 
tions best suited for the use of man. 
And as Colorado, New Mexico and all the middle west is benefited, in like 
degree your business interests will be improved and perpetuated. = #
