ASSEMBLING. 349 



males were liberated from station 3, half a mile to leeward 

 from station 1. No males reached the first station, but the 

 rain which fell from 11 a.m. till night may have prevented 

 the males from flying. 



Experiment JSfo. 4. 

 Weather, fair. Wind, north to east ; average movement, 

 10 miles. Two traps, containing six females each, were set 

 up at 10.30 A.M. Forty marked males were liberated at 

 10.45 A.M. from station 2, one-fourth of a mile from the first 

 station, and thirty-eight marked males were liberated at 

 10.55 A.M. from station 3, one-half a mile from the first sta- 

 tion. At 3.30 P.M. one male moth appeared in the vicinity 

 of the first station. An attempt to capture it was unsuccess- 

 ful. In all probability it came from either station 2 or 3, 

 since there were no infested areas in the direction toward 

 which the wind was blowing. 



Experiment JSfo. 5. 

 Cloudy. Wind, east ; average movement, 9 miles. Two 

 traps, containing six female moths each, were set up at 8 

 A.M. Nine marked males were liberated at 8.30 a.m., one- 

 fourth of a mile to leeward of the first station, and nine 

 marked males were liberated at 9 a.m., half a mile to lee- 

 ward of station 1. None of these males reached station 1. 



Experiment JSfo, 6. 

 Damp and cloudy, with light rains at intervals until 2 p.m.

 containing a single female moth, was set up at 1.45 p.m. 

 Six marked males were liberated at 2.10 p.m., 427 yards 

 to leeward of the first station, and fifty marked males 

 were liberated at 2.30 p.m., at station 3. This station was 

 located 713 yards to leeward of the first station. At 3.30 

 P.M. one male from station 2 reached the trap, and at 4.15 

 P.M. one from station 3.
