At length, emboldened by hunger, several hundred birds ventured through the tunnel, and took up their quarters actually in Nina's Hive.

Congregating in the large hall, the half-famished creatures did not hesitate to snatch bread, meat, or food of any description from the hands of the residents as they sat at table, and soon became such an intolerable nuisance that it formed one of the daily diversions to hunt them down; but although they were vigorously attacked by stones and sticks, and even occasionally by shot, it was with some difficulty that their number could be sensibly reduced.
By a systematic course of warfare the bulk of the birds were all expelled, with the exception of about a hundred, which began to build in the crevices of the rocks.

These were left in quiet possession of their quarters, as not only was it deemed advisable to perpetuate the various breeds, but it was found that these birds acted as a kind of police, never failing either to chase away or to kill any others of their species who infringed upon what they appeared to regard as their own special privilege in intruding within the limits of their domain.
On the 15th loud cries were suddenly heard issuing from the mouth of the principal gallery.
"Help, help! I shall be killed!" Pablo in a moment recognized the voice as Nina's.

Outrunning even Ben Zoof he hurried to the assistance of his little playmate, and discovered that she was being attacked by half a dozen great sea-gulls, and only after receiving some severe blows from their beaks could he succeed by means of a stout cudgel in driving them away.
"Tell me, Nina, what is this ?" he asked as soon as the tumult had subsided.
The child pointed to a bird which she was caressing tenderly in her bosom.
"A pigeon!" exclaimed Ben Zoof, who had reached the scene of commotion, adding: "A carrier-pigeon! And by all the saints of Montmartre, there is a little bag attached to its neck!" He took the bird, and rushing into the hall placed it in Servadac's hands.
"Another message, no doubt," cried the captain, "from our unknown friend.

Let us hope that this time he has given us his name and address." All crowded round, eager to hear the news.
