Fig. 2. Is a graphical diagram showing* how high the tem- 

 perature goes in summer and how low in winter, at eleven 

 different points in Utah. The diagram is based upon data 

 taken for five years, ending- with 1895.

When the trees were set, there were from ten to fifteen in- 

 dividuals in each of the forty species, placed in rows nine feet 

 apart, with a distance between trees in a row of .nine feet; but 

 in the struggle for room and soil a number of the trees have 

 died, and the distances apart are now much farther than those 

 named. The planting-, cultivating- and irrigating- have been 

 about the same as would be given an orchard, except that the 

 cultivation ceased at the sixth summer. This experiment 

 covers about two acres. 



While it is not the intention to deal much in this bulletin 

 with the last experiment started, yet it is in place to briefly in- 

 troduce it, for references will be made to it farther along- in 

 discussing- the various species; and, in the future, all work in 

 tree-planting- will be done in this plantation. The experiment 

 covers five acres, each acre forming a plat which is divided into 

 two equal parts. The plats and their divisions are arranged
