DEATH OF A VETERAN
There was buried on Saturday at Linlithgow one of the best known and pawkiest** men in the village - Mr. Robert Dumbreck. In the days when the county town was famous for boots and shoes, 'Bob' was taught his trade there and when the oil works at Champfleurie were a going concern, he shifted his place of business to Kingseavil. When the oil works went into liquidation, he continued to ply his trade at Winchburgh. In his youth, he joined the famous Militia, and did his six weeks' training annually. He was an ardent Volunteer, and was often to be seen at the targets at Hilty, Linlithgow. A keen church-man, he was the 'father' of the session of South Abercorn Church. He was the last of three brothers who died within recent years, and all of whom were interested in the Volunteer movement. He is survived by his wife.
