South American variety, it docs not follow that it will be adapted to our 

 conditions. All conditions of climate are found in these regions, from those 

 of the torrid tropical lowlands to those at the altitude of perpetual snows. 

 The regions from which the greater majority of our new introductions have 

 come are the highlands of Mexico ranging from about four thousand five 

 hundred to eight thousand feet in altitude; notably Atlixco, 7000 feet; 

 Qucrctaro, GOOD feet; Guanajuato, 6800 feet; and Guadalajara, 5400 feet. 

 The climatic conditions of these regions are strikingly similar to those of 

 much of California ; in parts the rainfall is even less than that which most 

 of Southern California enjoys. Much, then, is to be expected from fruits 

 of these districts. Practically the whole of Central and South America 

 remains to be explored. Travelers report types and varieties of the avocado 

 at the present time unknown to our horticulture. No one can accurately 

 predict the extent to which this fruit may be cultivated in the future. 



The importation of the avocado from these regions south of the United 

 States has been successfully done ])y three parties in Southern California, — 

 Mr. D. E. Clower of Monrovia. Mr. A. R. Rideout of Whittier, and the West 

 India Gardens of Altadena. 



One hears and reads of the so-called imported varieties without knowing 

 just what has been accomplished along that line, and it is in order to show 

 the extent of this work, that the following list is presented. It gives as 

 completely as possible those varieties that have been imported up to the 

 present time. Wherever possible the complete pomological description is 

 given, but this is manifestly impossible in all cases, as the material is not 

 available. When all have fruited in this country, there may be some 

 variation from the parent type. However, all conditions are so similar to 

 those of its native home that it is doubtful if there Avill be much deviation 

 from type or from the time of the fruiting season. 



The following three varieties were introduced by D. E. Clower of 

 Monrovia, California, from ^lexico and South America. He has also several 

 several other varieties under trial.
