But the decisive factor in establishing that exhilarating 'sense of wonder' in my youthful imagination was the discovery about that time of back numbers of American science fiction magazines to be bought quite cheaply in stores like Woolworths. The happy chain of economic circumstances by which American newstand returns, sometimes sadly with the magic cover removed or mutilated, ballasted cargo ships returning to English ports and the colonies, must have been the mainspring of many an enthusiastic hobby devoted to reading, discussing, perhaps collecting and even writing, science fiction—or 'scientifiction' as Hugo Gernsback coined the tag in his early Amazing Stories magazine. Gernsback was a great believer in reader participation; in 1936 I became a teenage member of the Science Fiction League sponsored by his Wonder Stories. Earlier he had run a competition in its forerunner Air Wonder Stories to find a suitable banner slogan, offering the prize of 'One Hundred Dollars in Gold' with true yankee braggadacio.
