The Trail of the Hawk, by Sinclair Lewis, is the chronicle of an inveterate Rolling Stone... Carl Ericson, a born rebel against conventions, finds himself from boyhood up at war with the combined forces of family, school and society, all three of which unite in trying to mould him into the average colourless human being. Consequently throughout his earlier years he is in perpetual disgrace, at home, at school and at college... Thus it happens that we find Carl in early adolescence a friendless and penniless wanderer, undaunted and thrilling with a sense of freedom and the boundless opportunity of satisfying his unquenchable curiosity about life. ... The first of the three parts into which this chronicle is divided, "The Adventure of Youth," ... covers the formative years and helps to explain why Carl is what he is, and not otherwise. ... Part II, "The Adventure of Adventuring," ... is an undiluted joy. It is improbable, to be sure, almost burlesque, yet so joyous, so spontaneous, so kaleidoscopic in its varied scene and shifting action, that one must accept it with indulgent credulity. ... Packer in a department store, waiter in a third-class restaurant, mechanic in an automobile factory, chauffeur, professional tramp and candidate for the bread line, porter in a Bowery saloon, facing the problem of saving four dollars out of a weekly salary of eight, in order to gratify a new ambition, namely to see the Panama Canal, - such is a brief epitome of one phase of our Rolling Stone's career, a phase that all unconsciously is shaping him for bigger things. ... and the following year finds him in California, a partner in a profitable automobile repair shop. Then the big news reaches him of the first successful flights of Curtis and the Wright Brothers, and Carl recognises by instinct that here is the outlet for his pent-up energies, the one career for which his whole undisciplined nature has been crying out. Much has been written about aviation, both from the technical and the popular standpoint ; but it would be hard to find anywhere else in fiction any description that would give to the inexperienced a kindred thrill of breathless flight, of danger that is a fearful joy, and of confident omnipotence that is superhuman. And then, when this unrivalled "Hawk of the Air-men" is at the zenith of his powers, comes his third adventure, "The Adventure of Love." ... Of course, the inevitable happens: the Hawk has his wings clipped, flights are a thing of the past, a onfining, although lucrative office position and a conventional apartment on the Upper West Side begin to prey upon his nerves; and soon the happy couple are quarrelling acrimoniously and often. But ... you cannot cage a hawk for long ... (Frederic Taber Cooper) --- "The Trail of the Hawk" is a truly lifelike chronicle of the fortunes of 'Widow Ericson's boy Carl,' of Joralemon, Minn., who becomes 'Hawk' Ericson, the daring aviator, and marries a very nice girl indeed. They had promised to find new horizons for each other, and when the resources of a New York flat in the way of horizons are exhausted, they sail for South America... (Atlantic Monthly)
