Western Mail, Thursday 11 May 1933, page 2
THE "SOOLEM" BRIGADE.
Dear "Non-Com.," - I have read several accounts of sooling from time to time in "The Western Mail." Here is another. At the end of 1915, one Bill Cook was a porter at the Central Station, Perth, and one day he approached au old lady and carried her luggage to her compartment. For thanks the old dear looked up and said, "Why is a young man like you not at the front? My two sons are both at the front-one is in the Army Post Office in Cairo and one is an orderly in a hospital at Boulogne. You ought to be fighting, too!"
Cooky volunteered immediately and ran into the Pozieres barrages in July and August, 1916.
He often pondered over the old lady's two soldier sons - one in Cairo and one at Boulogne - and cursed all soolers.
