McLaren found his experiment so successful that he decided to build a
hedge twenty feet high, extending more than a thousand feet. He also
used the hedge extensively in the landscape design for the Palace of
Fine Arts.



The Sculptors



The department of sculpture was placed under the direction of one of the
most distinguished sculptors in the country. Karl Bitter, of New York,
whose death from an automobile accident took place a few weeks after the
Exposition opened. He gathered around him an extraordinary array of
co-operators, including many of the most brilliant names in the world of
art, with A. Stirling Calder as the acting chief, the man on the ground.
Though he did not contribute any work of his own, he was active in
developing the work as a whole, taking special pains to keep it in
character and to see that, even in it its diversity, it gave the
impression, of harmony.

Calder welcomed the chance to work on a big scale and to carry out big
ideas. With Bitter he visited San Francisco in August, 1912, for a
consultation with the architectural commission. Minutely they went over
the site and examined the architectural plans. Then they picked the
sculptors that they wished to secure as co-operators.

In December, 1912, Bitter and Calder made another visit to San Francisco
