duction of cattle in the United States by the old system of wide 
herd ranging is practically at an end. Development here must 
now take the form of intensive methods of cattle production, 
upon relatively small areas. It is the problem of land scarcity 
that now faces the grazing industry. In this emergency, we 
find millions of acres of land upon which the supply of ordinary 
forage plants is so small, and is found during such restricted 
portions of the year, that grazing cannot be profitably conducted 
there, but which support an amount of cactus vegetation capable 
of supplying an almost limitless a . fodder, provided that 
a method can be found for using it. his condition, were 
there no other, would render the iG. ve cactus for fodder 
one of the most important to which governments could direct 
their attention, but there is another, the importance of which is . 
not less. It has been found in feeding cactus to cattle, that they 
can subsist upon it without the addition of any other water 
supply, there being about 8 gallons of water per hundred pounds, 
and probably more in some species not yet tested, so that it at 
once provides a method of cattle production where there is no 
water supply. It is perhaps too much to see. that the successful 
raising of cattle by means of upported supply of 
cactus pulp, of the sort now ane is eee but it can be 
affirmed that this supplv is capable of preserving the lives of 
great herds during temporary periods of scarcity of fodder and 
water. There are furthermore good grounds for hoping that 
through the process of plant breeding and improvement by 
cultivation, the character of cactus fodder can be greatly im- 
proved as to its nutritive ratio and value, and that processes of 
separation and manufacture can be devised which will render 
it available for many uses not now practicable. 
The results of the use of cactus fodder up to the present time 
indicate that its value, in kind as well as in amount, is almost the 
exact equivalent of that of green corn fodder, and that, in order 
to give the animal the fodder ratio required by the laws of 
nutrition, some richer fodder, as grain, must be fed with it. Fed 
in this way, and without any additional water supply, milk cattle 
were found to thrive without any apparent deterioriation. It
