Telescope Observations of Migrating Birds.— At TJrbana, lUinois, 

 between 9.45 and 10.45 p. m. on the seventh of last October, the writer 

 watched migrating birds through a four-inch telescope directed toward 

 the moon. The diversity in the direction of the flight on this evening 

 seems worthy of record. Out of a total of fifty-four birds, forty-two were 

 flying in a general southeriy direction, about one-half of these passing 

 directly southward, while others were headed southwest or southeast. A 

 few passed nearly eastward or westward. The remaining twelve, or 

 nearly one-fourth of the entire number, were flying in a general northerly 

 direction. In determining the direction it was assumed that the flight 

 in all cases was horizontal. Between 9 and 9.20 on the same evening 

 Professor Joel Stebbins, of the department of astronomy, counted thirteen 

 birds flying southward and five flying northward. The wind was from 

 the southeast, and had a velocity of only five miles an hour, as shown 

 "by an anemometer record. The temperature at 9 p. m. was 52° P. 



Huron, and the cold and snow combined overcame many of them, so that 

 they fell in the lake and were drowned. 



Thanksgiving day fell on the 18th, and Mr. Newton Tripp of Forest, 

 spent the day on the lake shore, near Port Franks, and observed hundreds 

 of birds on the shore dead, cast up by the waves. He wrote me about 

 it next day, calculating 5000 dead birds to the mile, and I took the first 

 train to the scene of the tragedy and drove out to the lake shore that 

 night. On the morning of the 21st, I patrolled the beach south from 

 Grand Bend, and after covering several miles and seeing only a few dead 

 birds, I came at last to the region of death. At first the birds were not 

 very close together, but eventually became so plentiful that in one place 

 I put my foot on four, and saw as many as a dozen in four or five feet. 



I began a census at once, which I continued until the lengthening shad- 

 ows warned me to hurry on to the river so as to cross in daylight, but in. 

 the two or three hours spent in the count I recorded the following: 



1 Black-throated Green Warbler, 4 Robins, 



1 Yellow Rail, 5 Fox Sparrows, 



1 Blue-headed Vireo, 5 Savanna Sparrows, 



1 Red-eyed Vireo, 5 Palm Warblers, 



1 Yellow-bellied Sapsucker, 7 Myrtle Warblers, 



2 Black-throated Blue Warblers, 12 Lincoln Sparrows, 



3 Flickers, 15 Ruby-crowned Kinglets,
