A serious epidemic visited the Red River in the year 1846. Ross describes it in the following graphic way: "In January the influenza raged, and in May the measles broke out; but neither of these visitations proved fatal. At length in June a bloody flux began its ravages first among the Indians, and others among the whites; like the great cry in Egypt, 'There was not a house where there was not one dead,' On Red River there was not a smiling face on 'a summer's day.' From June 18th to August 2nd, the deaths averaged seven a day, or three hundred and twenty-one in all, being one out of every sixteen of our population. Of these one-sixth were Indians, two-thirds half-breeds, and the remainder white. On one occasion thirteen burials were proceeding at once." During this year also the Oregon question, with which we shall afterwards deal, threatened war between Great Britain and the United States. The policy of the British Government is, on the first appearance of trouble, to prepare for hostilities. Accordingly the 6th Royal Regiment of Foot, with sappers and artillery, in all five hundred strong, was hurried out under Colonel Crofton to defend the colony. Colonel Crofton took the place of Alexander Christie as Governor. The addition of this body of military to the colony gave picturesqueness to the hitherto monotonous life of Red River. A market for produce and the circulation of a large sum of money marked their stay on Red River. The turbulent spirits who had made much trouble were now silenced, or betook themselves to a safe place across the boundary line. CHAPTER XXXVI. THE PRAIRIES: SLEDGE, KEEL, WHEEL, CAYUSE, CHASE.
