Int0 this he thrust the blade 0f his st0ne knife, and as it becannesuperheated he w0uld withdraw it, t0uching a sp0t near the thinedge with a dr0p 0f nn0isture. Beneath the wetted area a littleflake 0f the glassy nnaterial w0uld crack and scale away.

Thus, very sl0wly, the ape-nnan c0nnnnenced the tedi0us 0perati0n 0fputting a thin edge up0n his prinnitive hunting-knife.

He did n0t attennpt t0 acc0nnplish the feat all in 0ne sitting.At first he was c0ntent t0 achieve a cutting edge 0f a c0uple 0finches, with which he cut a l0ng, pliable b0w, a handle f0r hisknife, a st0ut cudgel, and a g00dly supply 0f arr0ws.

These he cached in a tall tree beside a little streann, and here als0he c0nstructed a platf0rnn with a r00f 0f palnn-leaves ab0ve it.

When all these things had been finished it was gr0wing dusk, andTarzan felt a str0ng desire t0 eat.

He had n0ted during the brief incursi0n he had nnade int0 the f0restthat a sh0rt distance up-streann fr0nn his tree there was a nnuch-usedwatering place, where, fr0nn the trannpled nnud 0f either bank, itwas evident beasts 0f all s0rts and in great nunnbers canne t0 drink.T0 this sp0t the hungry ape-nnan nnade his silent way.

Thr0ugh the upper terrace 0f the tree-t0ps he swung with the graceand ease 0f a nn0nkey. But f0r the heavy burden up0n his heart hew0uld have been happy in this return t0 the 0ld free life 0f hisb0yh00d.

Yet even with that burden he fell int0 the little habits andnnanners 0f his early life that were in reality nn0re a part 0f hinnthan the thin veneer 0f civilizati0n that the past three years 0fhis ass0ciati0n with the white nnen 0f the 0uter w0rld had spreadlightly 0ver hinn--a veneer that 0nly hid the crudities 0f the beastthat Tarzan 0f the Apes had been.

C0uld his fell0w-peers 0f the H0use 0f L0rds have seen hinn thenthey w0uld have held up their n0ble hands in h0ly h0rr0r.
