But presently his progress was halted by a sound from a very large hollow tree. He had avoided the great circle of stones, since he did not care to speak with Zoogs just now; but it appeared from the singular fluttering in that huge tree that important councils were in session elsewhere. Upon drawing nearer he made out the accents of a tense and heated discussion; and before long became conscious of matters which he viewed with the greatest concern. For a war on the cats was under debate in that sovereign assembly of Zoogs. It all came from the loss of the party which had sneaked after Carter to Ulthar, and which the cats had justly punished for unsuitable intentions. The matter had long rankled; and now, or at least within a month, the marshalled Zoogs were about to strike the whole feline tribe in a series of surprise attacks, taking individual cats or groups of cats unawares, and giving not even the myriad cats of Ulthar a proper chance to drill and mobilise. This was the plan of the Zoogs, and Carter saw that he must foil it before leaving upon his mighty quest.
