Allotment of range to animals not affected by II. Jioopesii. — It has 
been shown that cattle are seldom affected by H. Jioopesii and horses 
rarely if ever. A partial solution of the difficulty may be made 
in some cases by allotting sneezeweed ranges to horses or cattle 
rather than to sheep. 
Management of range to secure abundance of forage. — H. Jioopesii is 
not eaten because of its attractiveness to grazing animals, but is 
taken after the supply of other forage plants has been exhausted. On 
ranges where H. Jioopesii is abundant, but accompanied by a sufficient 
supply of other plants, sneezeweed poisoning seldom or never occurs. 
It is on overgrazed ranges, when little is left but H. Jioopesii, that the 
sheep are injured. Such ranges, because of the thriftiness of the 
plant, grow rapidly worse. It is obvious that an attempt should be 
made by proper management to restore the range. Theoretically 
this can be done by so restricting grazing as to permit an abundant 
growth of desirable range plants and natural reseeding. Unfortu- 
nately, as shown on pages 41-43, this is a long and somewhat dis- 
couraging process. Yet it seems clear that it is the only way by which 
the ranges can be made safe. Experience has shown that little can 
be expected from artificial reseeding. The practical question of so 
reducing allotments as to permit a range to become restored and re- 
main in good condition is a difficult one to handle, but it does not 
appear that there is any other way of handling the problem success- 
fully. This means that it is desirable that a range should never be 
stocked to its full capacity, but that a generous margin of safety 
should be left. It is appreciated that an ideal management of the 
range might work hardship on existing permittees, and that the 
handling of the problem demands not only trained ability and expe- 
rience to recognize the needs of a particular range, but a high order 
of tact to bring about desirable changes. 
PRACTICAL SUGGESTIONS FOR STOCKMEN ON THE RANGE. 
From the standpoint of the owner handling sheep on H. Jioopesii 
ranges the question of greatest importance is what practical methods 
he may use to eliminate or reduce his losses. His interest is in the 
deductions which may be made from the results of an investigation. 
It must be recognized that there are some things that man can not 
change, and that a thorough investigation of a subject may some- 
times simply show that under a given set of conditions nothing can 
be done in the way pi relief. It is a decided advantage, however, in 
such cases to know positively the facts and the conditions controlling 
the poisoning, so that one can combat the trouble intelligently and 
not waste his energies in attempting to do impossible things. 
By management of the flocks so as to avoid poisoning while on the 
range very much may be accomplished. Herders should be taught
