The number of orange trees planted to the acre is usually from forty-nine to sixty-nine; they then stand from twenty-five to thirty feet apart each way, and, thus planted, thrive and continue fruitful to a comparatively great age.  J. DeBarth Shorb, an enthusiastic believer in Los Angeles and oranges, says, “We have trees on our property fully forty years old, and eighteen inches in diameter, that are still vigorous and yielding immense crops of fruit, although they are only twenty feet apart.”  Seedlings are said to begin to bear remunerative crops in their tenth year, but by superior cultivation this long unproductive period my be somewhat lessened, while trees from three to five years old may be purchased from the nurserymen, so that the newcomer who sets out an orchard may begin to gather fruit by the fifth or sixth year.  When first set out, and for some years afterward, the trees are irrigated by making rings of earth around them, which are connected with small ditches, through which the water is distributed to each tree.  Or, where the ground is nearly level, the whole surface is flooded from time to time as required.  From 309 trees, twelve years old from the seed, DeBarth Shorb says that in the season of 1874 he obtained an average of $20.50 per tree, or $1435 per acre, over and above the cost of transportation to San Francisco, commission on sales, etc.  He considers $1000 per acre a fair average at present prices, after the trees have reached the age of twelve years.  The average price throughout the county for the last five years has been about $20 or $25 per thousand; and, inasmuch as the area adapted to orange culture is limited, it is hoped that this price may not greatly fall for many years.

The lemon and lime are also cultivated here to some extent, and considerable attention is now being given to the Florida banana, and the olive, almond, and English walnut.  But the orange interest heavily overshadows every other, while vines have of late years been so unremunerative they are seldom mentioned.

This is pre-eminently a fruit land, but the fame of its productions has in some way far outrun the results that have as yet been attained.  Experiments have been tried, and good beginnings made, but the number of really valuable, well-established groves is scarce as one to fifty, compared with the newly planted.  Many causes, however, have combined of late to give the business a wonderful impetus, and new orchards are being made every day, while the few old groves, aglow with golden fruit, are the burning and shining lights that direct and energize the sanguine newcomers.
