plant could grow.

It was necessary to bring down from the Sacramento Valley rich soil
(fifty thousand cubic yards), and spread sixteen thousand cubic yards of
fertilizer over that, in order to maintain lawns, trees and shrubs.

An immense number of trees, ranging from thirty to sixty feet in height,
were moved from Golden Gate Park and the Presidio of San Francisco. It

were six inches high, in flats.

These little trees were transferred into other flats and placed on hot
beds. After six weeks of this treatment they were transferred to 12-inch
boxes. They remained there for a period of eight months and then were
