That hope was soon disappointed, and I became apprehensive that some accident had befallen him. Holes in the soft surface and yawning cracks formed rather a peculiar feature in that part of the country; and as my horse had fallen both on this day and the preceding, when at a canter, and as Mr. Cunningham was often seen at that pace, it was probable that he might have met with some severe fall, and lay helpless, not far, perhaps, from where he had last been seen. The nights were cold, and I was doubtful whether he could be still alive, so difficult was it to account otherwise for his continued absence under all the circumstances. SOUTER AND MURRAY SENT BACK ALONG THE TRACK. April 20. After another night of painful anxiety the dawn of the THIRD day of Mr. Cunningham's absence brought some relief, as daylight renewed the chance of finding him, or of his finding us by our line, as he might have endeavoured to retrace his steps on losing the party, or he might be on our route still farther back than we had looked; but I was desirous that the natives whom we had left at Beny might be sent in search. I despatched the Doctor and Murray back along the line, the latter saying that he knew where Mr. Cunningham had turned off the road. It was not unlikely that the horse, if he had got loose, might have returned to where he had last drunk water (20 miles distant) therefore they were directed, if traces were not found nearer, to go so far back, and to promise the natives, if they could meet with any, tomahawks, etc. if they found the white man or his horse. No other course could be imagined. The line of route, as already stated, was a beaten road, and extended north and south. To the east of it and nearly parallel, at two or three miles distance, was the dry channel (Bullock creek) which led to the Bogan; on the north was our camp and the Bogan, whose general course was west, as well as our intended route, circumstances both known to Mr. Cunningham. Southward was the marked route, and the country whence we had come. Still however I thought it so likely that he must have gone to the north-west when we changed our route to north, that I determined, although my sprained ankle was painful, to examine again, and still more extensively, the country into which such a deviation must have led him. MY SEARCH SOUTH-SOUTH-WEST 40 MILES. April 21. I proceeded in a south-south-west direction (or South 17 degrees West by compass) or on a intermediate line between our route and the north-west line by which I had explored that country on the nineteenth, the men cooeying as before. We explored every open space; and we looked into many bushes, but in vain.
