RESULTS AT LINCOLN. 



Lincoln is located 65 miles west of Roswell, between El Capitan 

 Mountain and Sierra Blanca peak, a northerly spur of the Sacramento 

 Mountains, and has an altitude of some 5,700 feet. Through the 

 courtesy of Dr. J. W. Laws a number of bearing apple trees were set 

 aside for use in banding, and these furnished larvae throughout the 

 season. While the bands were placed on the trees early in May, no 

 larvae were found until June 13. Despite the fact that larvae oc- 

 curred more or less intermittently from that date until the season 

 closed, November 7, it would appear that only two full broods and 

 a partial third are found in the higher fruit-growing regions. 



The records found in Table LXI show that the maximum number 

 of larvae of the first brood of that season were found beneath the
