But how had MacNabb recognized this Ben Joyce in the quartermaster Ayrton? Here was the mystery that all wished to solve; and the major explained.
Since the day of his meeting with Ayrton he had suspected him. Two or three almost insignificant circumstances, a glance exchanged between the quartermaster and the farrier at Wimerra River, Ayrton's hesitation to pass through the towns and villages, his strong wish to order the Duncan to the coast, the strange death of the animals confided to his care, and, finally, a want of frankness in his actions,—all these facts, gradually noticed, had roused the major's suspicions.
However, he could form no direct accusation until the events that had transpired the preceding night. Gliding between the tall clumps of shrubbery, as was related in the previous chapter, he approached near the suspicious shadows that had attracted his attention half a mile from the encampment. The phosphorescent plants cast their pale rays through the darkness. Three men were examining some tracks on the ground, and among them he recognized the farrier of Black Point Station.
"Here they are," said one.
"Yes," replied another, "here is the trefoil of the hoofs again."
"It has been like this since leaving the Wimerra."
"All the horses are dead."
"The poison is not far away."
"There is enough here to settle an entire troop of cavalry. This gastrolobium is a useful plant."
"Then they were silent," added MacNabb, "and departed. I wanted to know more: I followed them. The conversation soon began again. 'A cunning man, this Ben Joyce,' said the farrier; 'a famous quartermaster, with his invented shipwreck. If his plan succeeds, it will be a stroke of fortune. Devilish Ayrton! Call him Ben Joyce, for he has well earned his name.' These rascals then left the wood of gum-trees. I knew what I wished, and returned to the encampment with the certainty that all the convicts in Australia are not reformed, in spite of Paganel's arguments."
