Meanwhile O'Malley , conveniently forgetful of Jan 's English nationality , was fond of borrowing the big hound for an hour or so together to help him in his educational efforts on behalf of Micky Doolan , the terrier . In such a matter Dick Vaughan and Jan were equally approachable and good-natured . Indeed , the pair of them had already done more than any of the different pupils ' masters in the matter of this revival of schooling among the barracks dogs . It happened toward four o'clock of a late autumn day that Dick Vaughan was engaged in Regina in attendance upon a great personage from Ottawa . O'Malley , having borrowed Jan 's services as helper , was busy giving tracking lessons to Micky Doolan on the prairie , half a mile from barracks . Chancing to look up from his work , O'Malley saw Sergeant Moore approaching on foot , with Sourdough -LRB- as ever -RRB- at his heels . He did not know that the sergeant had been watching him through binoculars from the barracks , and that he had spent a quarter of an hour in carefully devised efforts to exacerbate the never very amiable temper of Sourdough .
