SONIC NOISES 
The United States is now faced with the fast growing problem of noise. Noise from trucks, cars, machines and soon with the 
biggest contributor aircrafts, namely the supersonic jets. The United States now has 182 airports, within the next five years 
we expect to have 400 or more. 
At present commercial flights are not of the supersonic type, but the new British-French Supersonic Transport for civilian 
passenger use is expected within the next few months or sooner in some cases. These new aircrafts will increase greatly the 
rate of the present sonic booms. A popular misconception is that only one sonic boom is produced during a flight. Actually 
the boom follows continuously while the plane is flying faster than the speed of sound. These sonic booms have shattered 
windows, injured persons by flying glass, damaged ageless geological formations, and made a countless number of birds leave 
their nesting areas. The sonic booms have actually cracked the eggs of the young. 
Studies have not been completed on the total effects these sonic booms have made on all the different forms of wildlife, but 
it is known that where these sonic booms occur frequently the bird life is scarce, along with other forms of wildlife. 
Protest by civic groups has been most effective, and a number of programs are now under way. Among them are the Federal 
Aircraft noise-abatement program, and the program under the National Aeronautics and Space Administration to develop a 
quieter jet engine without sacrificing safety. Senator Clifford Case recently attempted to amend legislation to ban supersonic 
flights over land until more is known about them, the amendment was defeated. However, last July a law was passed which 
strengthens the FAA’s authority to provide control over noise and sonic booms of aircrafts. 
If you wish to do something to protect our homes, and our wildlife write to your congressman, the Department of 
Transportation and the FAA.

NEW MACHINE MOVES FULL—GROWN TREES 
A remarkable new machine has been developed which can move a full-grown tree, one to 12 inches in diameter, and up to 
50 feet tall in just 10 to 15 minutes. This machine may revolutionize the landscape business and also make it possible to save 
many trees which would otherwise be destroyed by bulldozing. 
America the Beautiful Fund sponsored a demonstration of the new machine for representatives of the government at 
Reston, Virginia. The new equipment makes it possible to scoop up a root ball seven feet in diameter and weighing up to 
7,500 pounds. The automatic tree-movers cost $10,000 and up; semi-automatic models sell for as little as $600.
