Park-making among the Sand Dunes.--For the creation of Golden Gate Park the park-makers of San Francisco had a series of sand hills, "hills on hills, all of sand-dune formation." The city obtained a strip of land lying between the bay and the ocean, yet close enough to the center of population to be cheaply and easily reached from all parts of the town. Work was begun in 1869, and has been prosecuted steadily since, with increasing appropriations, and the results are a credit to the city, Golden Gate Park, Mr. Frank H. Lamb says in his account of it in The Forester, having a charm that distinguishes it from other city parks. It has a present area of 1,040 acres, of which 300 acres have been sufficiently reclaimed to be planted with coniferous trees." It is this portion of the park which the visitor sees as one of the sights of the Golden Gate." As he rides through the park out toward the Cliff House and Sutro Heights by the Sea," he sees still great stretches of sand, some loose, some still held in place by the long stems and rhizomes of the sand grass (_Arundo arenaria_). This is the preparatory stage in park-making. The method in brief is as follows: The shifting sand is seeded with _Arundo arenaria_, and this is allowed to grow two years, when the ground is sufficiently held in place to begin the second stage of reclamation, which consists in planting arboreal species, generally the Monterey pine (_Pinus insignis_) and the Monterey cypress (_Cupressus macrocarpus_); with these are also planted the smaller _Leptospermum lævigatum_ and _Acacia latifolia_. These species in two or more years complete the reclamation, and then attention is directed to making up all losses of plants and encouraging growth as much as possible." The entire cost of reclamation by these methods is represented not to average more than fifty dollars per acre.
