seen. The changed appearance of the “bush” at Freetown, Sierra 
Leone, on the 25th of November, 1893, led him to call the attention of 
a native, who told him that locusts were coming. Ina short time 
huge black clouds appeared above the hills, and these first seen gave 
the idea that the whole of the sides of the hills, three miles off, were 
on fire; at 2.45 p. m. these supposed clouds reached Freetown and 
proved to be a continuous mass of locusts, which passed without in- 
termission till 5.10 p. m. Myriads settled, but made no apparent dif- 
ference in the size of the swarms. The whole town was covered with 
their excrement. At 9.45 a. m. the next day the stream began again, 
but not in such dense masses, and continued up to 1 p.m. The spe- 
cies has been found to be Pachytylus migratoroides originally described 
from Abyssinia.—Journal Royal Microscopical Society.
