 Pke.sent Time, —The fullowing list, arranged in sequence 

 according to the actual number of sales made during the 

 planting season of 1900-1'JOl, 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 ivhich are 

 more suitaljie and more effective tlian those for which 

 there is, at present, the greatest demand.

III. SELEPTroNS FOR SPECIAL PuRPOSER. —The diver- 

 sity of choice, rendered possible by the extent of desira- 

 ble material that is available, makes it somewhat difficult

2560. Picturesque field pine, remnant of a forest. 



to readily select the most suitable species for various 

 specific purposes. The following classified lists are 

 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. 



2561. Leaning tree in a clearing, showing its effort to 

 regain itself by producing upright branches. 



1. J^or Subtropical JSffrrf. — TlrAt there is in California 

 strong appreciation of subtropical effects in gardening 

 is shown by the great demand for dracasnas 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, with the addition of such 

 large-leaved herbaceous plants as cannas, colocasia, 

 cynaras, funkias, Ouvvera scabra, pampas grass, ver- 

 atrums, agaves, yuccas, aloes, Woodwardia radicans 

 and Hodcfersia podophylla, together with such shrubby 

 plants as bamboos, giant reed, the choicer varieties of 

 castor-bean, Senerio ftrandifolins, PoJygomtm Sachali- 

 nense and P. Sleboldi.

 useful for screen purposes if cut out before it becomes 

 straggling.
