example: this appears to be better than to plant the trees farther apart at fisst with some short-livcd trees or vines between them. as is sometimes recommended. The trees which are removed may be reset into a new or chard where they twill again come into profitable bearing.
 SOIL AND CLIMATE
 As to the kind of soil in which the olive succeeds, the same authority says that he has trees growing with- ont irrigation in black adobe, on stony hillsides: on adobe hillsidos, on table land with clay subsoil; in sandy lands made from the wash of mountains. with no difference in the bearing of the trees or the oil made" They arc knawn Go succeed where peach. apricot and ne4sarinc trees have been dcs- troyed by the black alkali and also in land SO rocky and steep that 1t cannot be plowed. Our virgin soils of Cali fornia are rich in lime and potash. two of the chief constituents required by the olive tree. Prof. Hilgard has stated that the substance of olive oil is taken entirely from the air. and that if the crop is made into oil and the pomace and all other olfal returned to the land from the outset it needs no other manure, lE the soil is fairly good one. It does not wear out the soil but if the fruit is pickled, returns should be made to the soil ana then potash and nitrogen are especially called for. The olive tree hourisheS under varied climatic conditions it. will withstand temperature of four teen degrees above zero; it succeeds in the dry interior valleys of the state where tho mnrcey during summer often ranges from 100 to l2O degrees in the shade. along the coast and on the high foothills of our mountain ranges. In Algeria. latitude B. it thriyes at an elevation of 4s00 feet above the level of the sea; in Italy at a height of 32o0 feet, and there is a bearing orchard in about tho latitude of Pomona situated upward of 5000 feet above the sea.
 IRRIGATION.
 The olive is q deep-rooted tree, hourishing in arid countries, and if properly Treated from it's first plant ing, requires but little water in moist locations other than the usual rainfall. There are many bearing trees in differ ent parts of the State that are not irrigated: while there are localities that will give the best results with out irrigation, there are no doubt other locations that need it, but in mest of such lands careful tilla.ye and in absence of better means. hauling water to them when needed win be time well spent, if the rewards of an olive orchard may thus be secured. But while the trees will do fairly well under conditions in which any other fruit tree would perish, it pays to give them generous culture.
 FOR THE STREET.
 The olive is coming into favor as street tree, combining several good qualities outside of it's protitabIenesr !:
 
 it Is not apt to be blown by hard wind storms: it does. not litter the ground with fallen leaves it's branches do not droop and obstruct the walk. if prop efly trimmed: it snot subject to have it's fruit stolen by persons passing; rc- quires little or no irrigation, and is generally regarded. as a very suitable tree for the purpose wherever it has been tested.
