In vol. iii. a poem, _Once upon a Time_, by Eliza Cook, has two illustrations (pp. 24, 25), which, tentative as they are, and not faultless in drawing, foreshadow the grace of his later work. In _Markham's Revenge_ (pp. 182-184) the artist is himself, as also in _Wanted a Diamond Ring_ (p. 210). _A Noctuary of Terror_ (pp. 294, 295), _First Love_ (p. 322), _The Unconscious Bodyguard_ (p. 359), are unimportant. _The Herberts of Elfdale_ (pp. 449, 454, 477, 505, 508), possibly the first serial Walker illustrated, is infinitely better. _Black Venn_ (p. 583), _A Young Wife's Song_ (p. 668), and _Putting up the Christmas_, a drawing group, complete the examples by this artist in vol. iii. Volume iv. contains: _Under the Fir-trees_ (p. 43), _Voltaire at Ferney_ (p. 66), a very poor thing, _The Fan_ (p. 75), _Bring me a light_ (pp. 102-105), _The Parish Clerk's Story_ (p. 248), _The Magnolia_ (pp. 263, 267), _Dangerous_ (p. 416), _An Old Boy's Tale_ (p. 499), _Romance of the Cab-rank_ (p. 585), and _The Jewel Case_ (p. 631). In vol. v. we find _Jessie Cameron's Bairn_ (p. 15), _The Deserted Diggings_ (p. 83), _Pray, sir, are you a Gentleman_? (pp. 127, 133), _A Run for Life_ (p. 306), _Cader Idris_ (p. 323), and a series of illustrations to _The Settlers of Long Arrow: a Canadian Story_ (pp. 421, 449, 477, 505, 533, 561, 589, 617, 645, 673, and 701). To volume vi. Walker contributes _Patty_ (pp. 126, 127), _A Dreadful Ghost_ (p. 211), and nine to Dutton Cook's _The Prodigal Son_ (pp. 449, 477, 505, 533, 561, 589, 617, 673, 701), which story, running into volume vii., has further illustrations on pp. 1, 29, and 57. _The Deadly Affinity_ (pp. 421, 449, 477), and _Spirit-rapping Extraordinary_ (p. 614) are the only others by the artist in this volume. The eighth volume has but one, _After Ten Years_ (p. 378), and _The Ghost in the Green Park_ (p. 309) is the only one in volume ix., and his last in the first series. Vol. i. of the New Series has the famous _Vagrants_ (p. 112) for one of its special art supplements.
