oriole, which is quite similar. Meadowlark was one imitation frequently 
repeated; wood pewee; English sparrow; grackle; a brief sequence of blue- 
bird; flicker; a few garbled notes of the red-eyed vireo; and so clear and 
distinct as to be unbelievable, the full whistling song of the cardinal. The 
cardinal imitation was so well produced that I looked twice at the starling 
to make sure that it was the one making the call. 
Several boys came by. They were on a turtle-hunting expedition. I told 
them that they were a little early. The turtles were probably still sleeping 
in the mud under the water. Leaving the island, I looked again into the sky. 
Winging their way high overhead was a long procession of gulls, silently 
moving northward. The temperature outside was cold. Inside, I was warm 
from the beautiful sight against the glow of the sinking western sun.

CONSERVATION Is GoopD BUSINESS. Natural Resources Department, Chamber 
of Commerce of the United States, Washington 6, D.C. 36 pages, 50c. 
This small publication tells the role of industry in the conservation story. 
It presents reports first made at a gathering of industry representatives 
at Houston and covers such areas as Petroleum, Forest Products, Electric 
Power, Mining, and Livestock. Each chapter contains a useful list of ref- 
erences and sources from which literature is available. 
This is an attempt by American business interests to persuade the public 
that at least some businessmen believe resource conservation makes good 
sense for both business and the country.

THE NATIONAL PARK WILDERNESS. National Park Service, Department of 
the Interior, Washington 25, D.C. 38 pages, free. 
At a time when the need for a National Wilderness Policy is being de- 
bated in Congress, this booklet sheds interesting light on the record of the 
National Park Service and its program to maintain wilderness values in 
our great primeval parks over the past 85 years. The work has been under- 
taken as part of the Mission 66 program. The brochure contains photo- 
graphs of scenes from Glacier National Park, Everglades, Yosemite, Grand 
Teton, Virgin Islands and Kings Canyon Parks, among others. 
Without passage of the Humphrey - Saylor Wilderness Bill, pressure on 
the National Park Service to modify its wilderness standards will grow 
without ceasing. At present, administrators are given considerable power 
to change long-established park policy. This is a most timely booklet.
