Bunter did! (Magnet).

After a terrible climb, hacking out handholds in the smooth ice every step of the way up, Sergeant Lionheart Logan of the Mounties was now clinging like a human fly to the face of an icy cliff, as smooth and treacherous as a giant pane of glass.
An Arctic blizzard, in all its fury, was buffeting his body, driving the blinding snow into his face, seeking to tear his fingers loose from their handholds and dash him to death on the jagged boulders which lay at the foot of the cliff a hundred feet below.
Crouching among those boulders were eleven villainous trappers who had done their best to shoot down Lionheart and his companion, Constable Jim Rogers—until the blizzard had blotted the two Mounties out of sight from below. (Wizard).

The second extract gets you some distance with the story, the first takes a hundred words to tell you that Bunter is in the detention class. Moreover, by not concentrating on school stories (in point of numbers the school story slightly predominates in all these papers, except the Thriller and Detective Weekly), the Wizard, Hotspur, etc., have far greater opportunities for sensationalism. Merely looking at the cover illustrations of the papers which I have on the table in front of me, here are some of the things I see. On one a cowboy is clinging by his toes to the wing of an aeroplane in mid-air and shooting down another aeroplane with his revolver. On another a Chinese is swimming for his life down a sewer with a swarm of ravenous-looking rats swimming after him. On another an engineer is lighting a stick of dynamite while a steel robot feels for him with its claws. On another a man in airman's costume is fighting barehanded against a rat somewhat larger than a donkey. On another a nearly naked man of terrific muscular development had just seized a lion by the tail and flung it thirty yards over the wall of an arena, with the words, "Take back your blooming lion!" Clearly no school story can compete with this kind of thing. From time to time the school buildings may catch fire or the French master may turn out to be the head of an international anarchist gang, but in a general way the interest must centre round cricket, school rivalries, practical jokes, etc. There is not much room for bombs, death-rays, sub-machine guns, aeroplanes, mustangs, octopuses, grizzly bears or gangsters.

Examination of a large number of these papers shows that, putting aside school stories, the favourite subjects are Wild West, Frozen North, Foreign Legion, crime (always from the detective's angle), the Great War (Air Force or Secret Service, not the infantry), the Tarzan motif in varying forms, professional football, tropical exploration, historical romance (Robin Hood, Cavaliers and Roundheads, etc.) and scientific invention. The Wild West still leads, at any rate as a setting, though the Red Indian seems to be fading out. The one theme that is really new is the scientific one. Death-rays, Martians, invisible men, robots, helicopters and interplanetary rockets figure largely; here and there there are even far-off rumours of psychotherapy and ductless-glands. Whereas the Gem and Magnet derive from Dickens and Kipling, the Wizard, Champion, Modern Boy, etc., owe a great deal to H. G. Wells, who, rather than Jules Verne, is the father of "Scientifiction." Naturally it is the magical, Martian aspect of science that is most exploited, but one or two papers include serious articles on scientific subjects, besides quantities of informative snippets. (Examples: "A Kauri tree in Queensland, Australia, is over 12,000 years old"; "Nearly 50,000 thunderstorms occur every day"; "Helium gas costs £1 per 1000 cubic feet"; "There are over 500 varieties of spiders in Great Britain"; "London firemen use 14,000,000 gallons of water annually," etc. etc.). There is a marked advance in intellectual curiosity and, on the whole, in the demand made on the reader's attention. In practice the Gem and Magnet and the postwar papers are read by much the same public, but the mental age aimed at seems to have risen by a year or two years—an improvement probably corresponding to the improvement in elementary education since 1909.

The other thing that has emerged in the post-war boys' papers, though not to anything like the extent one would expect, is bully-worship and the cult of violence.

If one compares the Gem and Magnet with a genuinely modern paper, the thing that immediately strikes one is the absence of the leader-principle. There is no central dominating character; instead there are fifteen or twenty characters, all more or less on an equality, with whom readers of different types can identify. In the more modern papers this is not usually the case. Instead of identifying with a schoolboy of more or less his own age, the reader of the Skipper, Hotspur, etc., is led to identify with a G-man, with a Foreign Legionary, with some variant of Tarzan, with an air ace, a master spy, an explorer, a pugilist—at any rate with some single all-powerful character who dominates everyone about him and whose usual method of solving any problem is a sock on the jaw. This character is intended as a superman, and as physical strength is the form of power that boys can best understand, he is usually a sort of human gorilla; in the Tarzan type of story he is sometimes actually a giant, eight or ten feet high. At the same time the scenes of violence in nearly all these stories are remarkably harmless and unconvincing. There is a great difference in tone between even the most bloodthirsty English paper and the threepenny Yank Mags, Fight Stories, Action Stories, etc. (not strictly boys' papers, but largely read by boys). In the Yank Mags you get real blood-lust, really gory descriptions of the all-in, jump-on-his-testicles style of fighting, written in a jargon that has been perfected by people who brood endlessly on violence. A paper like Fight Stories, for instance, would have very little appeal except to sadists and masochists.
