AN AMERICAN BAMBOO GROVE OPEN TO 

 INVESTIGATORS 



Research men connected with tlie state 

 and other institutions are invited to visit the 

 bamboo grove at Savannah on the Ogeechee 

 Road. This grove covers an acre of ground, 

 and the culms rise fifty-five feet into the air, 

 producing a dense forestlike effect with their 

 smooth dark green culms three and four 

 inches in diameter. It is the largest grove 

 of the Madane bamboo (.Phyllostachys ham- 

 husoides) east of the Mississippi and com- 

 parable in beauty to groves of similar size 

 in Japan. Any botanist who has never seen 

 a bamboo grove has waiting for him a thrill- 

 ing experience, for the sight of a giant grass 

 over fifty feet tall changes one's ideas of 

 grasses just as the sight of a victoria regia 

 changes one's ideas of water lilies or the dis- 

 covery of the pterodactyl changed our ideas 

 of lizards and birds. A simple laboratory, 

 which is being equipped with limited living 

 accommodations, stands in the center of the 

 grove, and its facilities axe at the disposal of 



the research workers of the Department of 

 Agriculture and other institutions upon ap- 

 plication to this office. 



While the grove is wonderfully interest- 

 ing at any time, it is peculiarly fascinating 

 about the middle of April when the new 

 shoots four inches in diameter are coming 

 through the ground and shooting skyward 

 at a gi'eat rate. 



Botanists to or from Florida should by all 

 means stop and see this grove. It lies twelve 

 miles from Savannah on a new concrete high- 

 way, the Ogeechee Eoad. Long distance tele- 

 phone central will connect anyone with the 

 " Government Bamboo Grove," and they can 

 talk with Mx. Eankin, the superintendent.

FLIGHTS OF HOUSE FLIES 



That the house fly not uncommonly makes 

 a journey of five to six miles in the space of 

 twenty-four hours is shown by experiments 

 conducted by the Bureau of Entomology, 

 United States Department of Agriculture. 

 The ease with which flies travel many miles 

 shows the importance of general sanitary 

 measures to destroy breeding places. Fly 

 flight tests were conducted in northern Texas, 

 where approximately 234,000 flies of many 

 diiferent species were trapped, then dusted 

 with finely powdered red chalk, and liberated. 

 Fly traps baited with food highly relished by 

 the flies were placed at measured intervals in 

 all directions from the points of release. By 

 means of these secondary traps, it was x>ossible 

 to determine the direction and flight of dif- 

 ferent species of flies. The tests showed that 

 the flies, after regaining their freedom, would 

 travel distances up to 1,000 feet in a few min- 

 utes. The screw-worm fly evidenced its 

 jKJwer to cover a half mile in three hours, 

 while the black blowfly traveled anywhere 

 from half a mile to eleven miles during the 

 first two days' release. The house fly covered 

 over six miles in less than twenty-four hours.
