No 500, July 14.
Now evident that mobilization mentioned our number 498 taking place on considerable scale and under unusual conditions as to secrecy. It has been determined that some of the newly mobilized men are being sent to Manchuria, but as yet unable to determine how many or whether any are being sent southern destination. Although Tokyo is alive with rumors as to purpose this mobilization there is no conclusive indication so far available.
