II. Trees Beino Most Extensively Planted at the 

 Present Time. — The following list, arranged in sequence 

 according to the actual number of sales made during the 

 planting season of 1900-1901, is compiled from data 

 furnished by John Rock, of the California Nursery Com- 

 pany, at Niles. The percentages refer only to the 

 seventeen species here enumerated, and not to the total 

 number of trees sold by the nursery, which has a large 

 and varied assortment of species many of -which are 

 more suitable and more effective than those for which 

 there is, at present, the greatest demand.

III. Selections for Special Purposes.— The diver-

 ble material that is available, makes it somewhat difficult

to readily select the most suitable species for various 

 specific purposes. The following classified lists arc 

 intended as suggestions to aid in making a suitable 

 selection; they are almost entirely restricted to species 



offered in the Californian trade, and are intended to be 

 suggestive only, and not by any means complete. New 

 species and varieties are constantly being added to the 

 nursery stocks, some of which will be found particularly 

 well adapted to certain conditions of climate and soil, 

 and will doubtless replace others now in use.

1. For Subtropical Et feet. — That there is in California 

 strong appreciation of subtropical effects in gardening 

 is shown by the great demand for dracsenas and such 

 large-leaved plants as palms, magnolias, bananas and 

 rubber-trees. That the effect produced by the planting 

 of such trees so often fails to be satisfactory is largely 

 due to one or both of two causes, — either unsuitable 

 location of the specimens or choice and association of 

 unsuitable species. To prevent a repetition of the first- 

 named error, the prospective tree-planter is recom- 

 mended to consult the article on Landscape Gardening 

 in Volume II; and to avoid the second, a selection from 

 the following list is suggested, witli the addition of such 

 large-leaved herbaceous plants as cannas, colocasia, 

 cynaras, funkias, Gunnera scaora, pampas grass, ver- 

 atrums, agaves, yuccas, aloes, Woodwardia radicans 

 and Rodgersia podophylla, together with such shrubby 

 plants as bamboos, giant reed, the choicer varieties of 

 castor-bean, Senecio grandifolius , Polygonum Sachali- 

 nense and P. Siebokli.

Eucalyptus Globulus can also be used effectively if 

 cut down periodically when the falcate leaves begin to 

 appear; it will continue to shoot up vigorously from the 

 same root for several years. Eucalyptus robusta is 

 useful for screen purposes if cut out before it becomes 

 straggling.
