Gist of Hebrew: Here lies an important young man of 18 years, Avraham Meir son of Shmuel Bury, left the land of the living on the 25 day of the month of Nissan in the year 5674, by the abbreviated date. May his soul be bound up in the bond of eternal life.
(The secular date 3 May 1914 corresponds to the Hebrew date of 7 Iyyar 5674 rather than 25 Nissan 5674.)
