10 KANGE 1NVP:STIGAT1<)NS IN ARIZONA. 



September 12 to 22, 1903. Adamana to Chin Lee, and return via Navajo. 

 September 24 to 25, 1903. Preseott to Mayer. 



October 6 to II, 1903. Tucson to Patagonia via Greaterville and Cottonwood, and 

 return via Sopori, Arivaca, Babuquivari Mountains, and Robles. 



This rather formal list takes no cognizance of the work done between 

 trains and on short stops at varions places along- the lines of railroad, 

 especially on the main line of the Santa Fe system, the Santa Fe, Pres- 

 cott and Phoenix, and the Santa Fe, Prescott and Eastern railways, 

 between Needles and Gallup and between Phoenix and Ash Fork. 



Arizona has a total area of 72,332,800 acres, of which only 264,521 

 acres are improved; but there are reserved 19, 721:, 717 acres, accord- 

 ing to Governor Brodie's report to the Secretarj^ of the Interior in 

 1902. A part of this reserve land is available for grazing purposes 

 under certain restrictions, grazing being allowed upon all the forest 

 reserves excepting the Grand Canyon, and of course the Indians raise 

 a great deal of stock upon their reservations. Taking everything into 

 consideration, there are probal)ly upward of 65,000,000 acres available 

 for stock raising. 



According to the Twelfth Census (1900), there were in the Territory 

 1,033,63-1 units of stock, sheep and goats being calculated at the rate 

 of 6 to 1 bovine animal in relation to pasture consumption. Unfor- 

 tunately no distinction was made in these Census reports between 

 range and farm stock, so that it is impossible to determine from the 

 lists the number of stock supported on native pastures. All that can 

 be said is that there was in the Territory in 1900 one animal unit to 

 approximatel}" every 65 acres of land availal)le for stock purposes. 

 This includes farm animals as well as range stock. It is interesting 

 to compare these figures with those given by Mr. C. W. Gordon in 

 the statistics of the Tenth Census. Here Mr, Gordon, who made an 

 elaborate report upon the conditions, as well as the number of animals, 

 estimated that in 1880 there were 229,062 units of stock, occupying 

 43,750 square miles of range lands, or 1 unit to 122.24 acres.. 



THE SMALL INCLOSURE. 



A full description of the small inclosure was given in Bulletin No. 4 

 of this series, after the tirst planting was made in the winter of 1901. 

 It will not be necessary, therefore, to enter into the d«^tails of the 

 work on this area any further than to discuss briefly the results which 

 have l)een secured by the experiments which were suggested at that 

 time, and which have been carried on since with such modifications and 

 changes as further light and experience have shown to be necessary. 



As stated in Bulletin No. 4, some sixty species of forage plants 

 were sown, the Avork being begun on the loth and hnished on the 23d 

 of January, 1901. These plants were given various forms of treat- 

 ment, the seed of some being covered Ijy a disk harrow and of others
