And straightway comes over the water from some distant cove the same password repeated, where the next in seniority and girth has gulped down to his mark; and when this observance has made the circuit of the shores, then ejaculates the master of ceremonies, with satisfaction,tr-r-r-oonk! and each in his turn repeats the same down to the least distended, leakiest, and flabbiest paunched, that there be no mistake; and then the howl goes round again and again, until the sun disperses the morning mist, and only the patriarch is not under the pond, but vainly bellowing troonk from time to time, and pausing for a reply.
