CONTROL OF GRAZING LANDS. 59 



The study ot these eoUectioiis has I'esidled in the' disooveiy of about 

 75 species of grasses which iuid not before been described. The vari- 

 ous buUetins containino- studies on American grasses have been based 

 in great part upon the study of these large collections. In fact, nearl}^ 

 all the publications of the Division are based either directly or indi- 

 rectly upon the field work which has been done. 



Resides the collection of specimens, a collection of seeds of the native 

 grasses has l)een made a ver3^ important feature of tlie field \vork, 

 especially during the past two seasons. Recognizing tln^ great \'alue 

 and importance of the native forage products, sj>ecial efiorts have 

 been made to show the possil)ilities in the way of cultivation and to 

 encourage the production of seed by seedsmen. This will no (l()ul)t 

 be done as soon as there is a suflicient demand foi- them. During the 

 past season over four tons of seed of native grasses and forage plants 

 were collected -md distributed. As these seed were nearly all col- 

 lected by hand, the amount of labor recpiired may be appreciated. 

 Besides the specimens and seeds, roots and sheaves have also been col- 

 lected in ([uantit}'. In some cases it is impracticable to secure seed of 

 a desirable plant, and in sucn cases roots were taken up and forwarded 

 to vai'ious points for transplanting. Bufi'alo grass {BtdJn/./s dactij- 

 (o/dis). IVu-muda grass {(^ynodon dactyloii)^ Texas bhu; grass {Poa 

 ((r<n-hiuf<'i'<()^ and others have been established and propagated at 

 various i)laces in this way. The sheaves have proven very useful for 

 purposes of illustration and exhibition. A large collection was on 

 exhil)ition at the Paris Exposition, and a collection has also been sent 

 to the Pan-American Exi)osition. Another verv interestinp- and 

 important result of the work has been the securing of photographs 

 illustrating all features of the work. In the neighl)orhood of a thou- 

 sand negatives have thus been obtained. These are invaluable for 

 illustrating the various publications of the Division. From them a 

 series of lantern slides has also been made for use in connection with 

 lectures and various features of the Division's work. 



CONTROL OF GRAZING LANDS. 



In the following paragraphs a brief account is given of the various 

 methods adopted in other countries for controlling the public grazing 

 lands. These may prove helpful in devising some method of conti-ol- 

 11 ng our own grazing lands. 



THE AUSTRALIAN SYSTEMS. 



An examination of the methods pursued by the different Australian 

 colonies in the management of their grazing lands may \w, of interest 

 and benefit in this connection. There are vast portions of the interior 

 of Australia where, on account of an insufficient supply of moisture,
