LOOKING ACROSS ONE YEAR'S GROVE TOWARDS FARM BUILDINGS, SAN DIEGO, CAL., MUNICIPAL FOREST. and the trees, which are about one foot in height, set into the ground about four inches so as to be well into the moist earth. No water is used in the planting, and none afterward. After the trees are planted they are cultivated until a thorough dust mulch is estab- lished. This requires about five culti- vations extending up into June when no more care is necessary until the rains of the next winter. In the fol- lowing spring a mulch is again formed by stirring up the ground between the trees. After one year's growth many of the trees are ten feet in height with a diameter at the base of fully two inches. Trees set upon the same soil without cultivation have not equalled this growth in two years' time. After the first year's planting was completed a nursery was established with a capacity of several hundred thousand trees a year for carrying on the work. The trees grown for the 1912 planting included about seven species of Eucalyptus and a few species of Acacias; numerous ornamental trees were also propagated for use along the drives and boulevards. Among these were a few thousand of the Torrey Pines (Pinus Torreyana), which were grown for enlarging the grove of these trees which is located upon the city land. With the exception of a few trees found upon one of the coast islands these are the only trees of this species in existence. About two hun- dred and fifty acres have been planted.
