His search through the various books convinced him that he had discovered all the different kinds of bugs most often repeated in combination, and these he arranged in proper order with great ease because of the frequency with which he had perused the fascinating alphabet picture book.
His education progressed; but his greatest finds were in the inexhaustible storehouse of the huge illustrated dictionary, for he learned more through the medium of pictures than text, even after he had grasped the significance of the bugs.
When he discovered the arrangement of words in alphabetical order he delighted in searching for and finding the combinations with which he was familiar, and the words which followed them, their definitions, led him still further into the mazes of erudition.
By the time he was seventeen he had learned to read the simple, child's primer and had fully realized the true and wonderful purpose of the little bugs.
No longer did he feel shame for his hairless body or his human features, for now his reason told him that he was of a different race from his wild and hairy companions. He was a M-A-N, they were A-P-E-S, and the little apes which scurried through the forest top were M-O-N-K-E-Y-S. He knew, too, that old Sabor was a L-I-O-N-E-S-S, and Histah a S-N-A-K-E, and Tantor an E-L-E-P-H-A-N-T. And so he learned to read. From then on his progress was rapid. With the help of the great dictionary and the active intelligence of a healthy mind endowed by inheritance with more than ordinary reasoning powers he shrewdly guessed at much which he could not really understand, and more often than not his guesses were close to the mark of truth.
There were many breaks in his education, caused by the migratory habits of his tribe, but even when removed from his books his active brain continued to search out the mysteries of his fascinating avocation.
Pieces of bark and flat leaves and even smooth stretches of bare earth provided him with copy books whereon to scratch with the point of his hunting knife the lessons he was learning.
Nor did he neglect the sterner duties of life while following the bent of his inclination toward the solving of the mystery of his library.
He practiced with his rope and played with his sharp knife, which he had learned to keep keen by whetting upon flat stones.
The tribe had grown larger since Tarzan had come among them, for under the leadership of Kerchak they had been able to frighten the other tribes from their part of the jungle so that they had plenty to eat and little or no loss from predatory incursions of neighbors.
Hence the younger males as they became adult found it more comfortable to take mates from their own tribe, or if they captured one of another tribe to bring her back to Kerchak's band and live in amity with him rather than attempt to set up new establishments of their own, or fight with the redoubtable Kerchak for supremacy at home.
Occasionally one more ferocious than his fellows would attempt this latter alternative, but none had come yet who could wrest the palm of victory from the fierce and brutal ape.
Tarzan held a peculiar position in the tribe. They seemed to consider him one of them and yet in some way different. The older males either ignored him entirely or else hated him so vindictively that but for his wondrous agility and speed and the fierce protection of the huge Kala he would have been dispatched at an early age.
Tublat was his most consistent enemy, but it was through Tublat that, when he was about thirteen, the persecution of his enemies suddenly ceased and he was left severely alone, except on the occasions when one of them ran amuck in the throes of one of those strange, wild fits of insane rage which attacks the males of many of the fiercer animals of the jungle. Then none was safe.
On the day that Tarzan established his right to respect, the tribe was gathered about a small natural amphitheater which the jungle had left free from its entangling vines and creepers in a hollow among some low hills.
The open space was almost circular in shape. Upon every hand rose the mighty giants of the untouched forest, with the matted undergrowth banked so closely between the huge trunks that the only opening into the little, level arena was through the upper branches of the trees.
Here, safe from interruption, the tribe often gathered. In the center of the amphitheater was one of those strange earthen drums which the anthropoids build for the queer rites the sounds of which men have heard in the fastnesses of the jungle, but which none has ever witnessed.
Many travelers have seen the drums of the great apes, and some have heard the sounds of their beating and the noise of the wild, weird revelry of these first lords of the jungle, but Tarzan, Lord Greystoke, is, doubtless, the only human being who ever joined in the fierce, mad, intoxicating revel of the Dum-Dum.
From this primitive function has arisen, unquestionably, all the forms and ceremonials of modern church and state, for through all the countless ages, back beyond the uttermost ramparts of a dawning humanity our fierce, hairy forebears danced out the rites of the Dum-Dum to the sound of their earthen drums, beneath the bright light of a tropical moon in the depth of a mighty jungle which stands unchanged today as it stood on that long forgotten night in the dim, unthinkable vistas of the long dead past when our first shaggy ancestor swung from a swaying bough and dropped lightly upon the soft turf of the first meeting place.
On the day that Tarzan won his emancipation from the persecution that had followed him remorselessly for twelve of his thirteen years of life, the tribe, now a full hundred strong, trooped silently through the lower terrace of the jungle trees and dropped noiselessly upon the floor of the amphitheater.
The rites of the Dum-Dum marked important events in the life of the tribe—a victory, the capture of a prisoner, the killing of some large fierce denizen of the jungle, the death or accession of a king, and were conducted with set ceremonialism.
Today it was the killing of a giant ape, a member of another tribe, and as the people of Kerchak entered the arena two mighty bulls were seen bearing the body of the vanquished between them.
They laid their burden before the earthen drum and then squatted there beside it as guards, while the other members of the community curled themselves in grassy nooks to sleep until the rising moon should give the signal for the commencement of their savage orgy.
For hours absolute quiet reigned in the little clearing, except as it was broken by the discordant notes of brilliantly feathered parrots, or the screeching and twittering of the thousand jungle birds flitting ceaselessly amongst the vivid orchids and flamboyant blossoms which festooned the myriad, moss-covered branches of the forest kings.
At length as darkness settled upon the jungle the apes commenced to bestir themselves, and soon they formed a great circle about the earthen drum. The females and young squatted in a thin line at the outer periphery of the circle, while just in front of them ranged the adult males. Before the drum sat three old females, each armed with a knotted branch fifteen or eighteen inches in length.
Slowly and softly they began tapping upon the resounding surface of the drum as the first faint rays of the ascending moon silvered the encircling tree tops.
As the light in the amphitheater increased the females augmented the frequency and force of their blows until presently a wild, rhythmic din pervaded the great jungle for miles in every direction. Huge, fierce brutes stopped in their hunting, with up-pricked ears and raised heads, to listen to the dull booming that betokened the Dum-Dum of the apes.
Occasionally one would raise his shrill scream or thunderous roar in answering challenge to the savage din of the anthropoids, but none came near to investigate or attack, for the great apes, assembled in all the power of their numbers, filled the breasts of their jungle neighbors with deep respect.
As the din of the drum rose to almost deafening volume Kerchak sprang into the open space between the squatting males and the drummers.
Standing erect he threw his head far back and looking full into the eye of the rising moon he beat upon his breast with his great hairy paws and emitted his fearful
