The Upper Limit of Avocado Cultivation in Guatemala. 



The city of Totonicapan, at an altitude of 8,500 feet, in western Guatemala, is the highest point at 

 which the avocado is cultivated in this Republic. Its existence here is precarious, as is shown 

 by the condition of this tree. Heavy frosts occur from time to time, and unless an avocado tree 

 is unusually hardy it may be injured severely. The only other subtropical fruit grown in Totoni- 

 capan is the matasano, or white sapote ( Casimiroa edulis). Apples, peaches, and pears are char- 

 acteristic of the region, but citrus fruits are not grown above altitudes of 7,500 feet. (Photo-
