Game Plentiful On Catalim.; Dozens of quail were seen al 
from Oracle to the Stratton Mine on the Catalinas while a 
mountain to attend the dedication of the Oatallna Naturn.l 
return trip on the 13th two white-tail deer crossed the r 
of the car, a doe and a buck. It is not uncommon to see 
deer along the road, according to local residents and thi 
game refuge. Summer tourists make early morning visits t 
near the hotel to watrh th  as'. 
Crop LandL The nrea of crop li'nd in the United States decreased 
13,000,000 acres between 1919 and 1924, according to studies made by the

Department of -riculture as reported in the Engineering News-Record&

During this same period the population increased by eight million or 
fully 7%. Despite the decreasod area, the total agricultural production 
increased about 13% or almost twice as rapidly as population. During the

same years the decrease in farm pop,1.2ation was about 6%. Fewer farmers

are producing from a sx. ller acreage of land more food and fibers than 
the increasing population is able to consume, at profitable prices to 
all farmers. t(Ed. These figures dispose lf the argument for the time 
being that forest land is now needed for the production of farm cr-Nps.)

Jackrabbits Difficult Problem of Bioogical Survey,: The mest difficult 
problem confronting the Biological Burvey today in New Mexico is that of

eradication of the jackrab.bit, according to M. A. E. Gray, head of the 
New Mexico division of the Survey. It is estim.ted that one-fourth tf 
the forage consiu'ed in New Mexico aimually is eaten by these aninils. 
Efforts t6 poison them have met with only meagre succeas as the food 
habits of the jackrabbit are so irregular that the kind of food it eats 
today may not be touched tomorrow. In northern states where the animals 
congregate around bay-stacks in winter, it is an easy n.tter to poison them

by the thousands, but poisoning them In New Mexico is a much more didficult

task. iabbit drives proved successful in some sections of the state

where the populntiol is thick enough to make drive practicable. Most 
sections, homevor, are too sparsely popul-.ted for this method of eradica-

tion to be feasible. Dr. V.lter P. Taylor of Tucson is nov attempting to

devise a plmu of coping with the jackrabbit problen.
