PI. 269. 
A YOUNG AVOCADO ORCHARD IN QUERETARO, MEXICO. 
(Persea americana Mill. See S. P. I. No. 46984.) 
Avocado growers in the United States will be interested in this illustration of a 5-year-old 
orchard in the canyada at Queretaro. The trees are all seedlings of the Mexican race. 
Alfalfa is planted as a secondary crop, and the soil is irrigated regularly. The results 
obtained from plantations of this kind are so much better than those obtained where the 
trees are planted indiscriminately and given no care that Mexicans are rapidly coming to 
realize the desirability of devoting more attention to the development of such plantations.
