DOMINION DAY.After several days of heavy artillery fire our troops were relieved, and the headquartersmoved to the north. Here a trench-line wastaken over from a British division, and here for the present we must leave them. When Dominion Day came they remembered with pride that they were the army of a nation, and those who were in the trenches displayed the Dominion flag decorated with the flowers of France, to the annoyance of the barbarians, who riddled it with bullets. Behind the lines the day was celebrated with sports and games, while the pipers of the Scottish Canadian battalions played “ a selection of national airs.”But the shouting baseball teams and minstrel shows, with their outrageous personal allusions, the skirl of the pipes, and the choruses of the well-known rag-times, moved men to the depth of their souls. For this is the first Dominion Day that Canada has spent with the red sword in her hand.
