Sept. 3, 1874.—A destructive earthquake occurred in Guate- 
mala; centering near the Volean del Fuego. Advices from 
Antigua state that, since the beginning of August, slight shocks 
had been felt, becoming more frequent toward the end of the 
month. From Aug. 27, the town of Duenos, and other places 
near the volcano named, felt shocks at short intervals, accom-

9 P.M. (one account says 8" 80", another 9" 18™), the most 
violent shock occurred. The movement was a series of vertical 
and horizontal impulses combined ; the direction was west to 
east, as noted by a swinging lamp. The shock was stated by 
one observer as lasting twenty-five or thirty seconds; by 
another as continuing in its intensity during four seconds and 
then gradually diminishing. Sounds like thunder were heard 
from the earth. Many other less violent shocks were felt dur- 
Ing the night, the principal one at 2 a. mM. In Antigua the 
church bells were rung by the vibration, about two dozen 
inhabited houses were destroyed and thirty-two lives lost. The 
town of Duenos was entirely ruined, and some persons were 
killed there and in neighboring villages. An eruption of cold
