I gather that _The Son of Tarzan_ (METHUEN) is the fourth of a _Tarzan_ series by Mr. EDGAR RICE BURROUGHS, who specialises in an exciting brand of hero, half ape, half man. _Tarzan père_ had been suckled and reared by a proud ape foster-mother, and after many jungle adventures had settled down as _Lord Greystoke_. This latest instalment of the _Tarzan_ chronicles finds the _Greystokes_ somewhat anxious about the restlessness and unconventional tastes of their schoolboy son, who inherits not only his father's vague jungle longings but all his explicit acquired characteristics, so that when, with the decent old ape, _Akut_, disguised as his invalid grandmother, he sails away from England and plunges into the wild he promptly becomes the terror of the jungle and bites the jugular veins of hostile man and beast with such a precision of technique that he becomes king of the ape-folk, as his father, _Tarzan_, had been before him. Plausibility, even within the limits of his bizarre plan, is not Mr. BURROUGHS' strong suit, but exciting incident, ingeniously imagined and staged, with swift movement, undoubtedly is. If the author wouldn't let his favourites off so easily and would give their enemies a better sporting chance, he would more readily sustain the illusion which is of the essence of real enjoyment in this kind of fantasy. But I imagine the normal human boy will find nothing whatever to complain of, and to him I chiefly commend this yarn. * * * * *
