"Landseer is sensitive, delicate, with a fine hand for manipulation,—up to all the finesse of the art; has brushes of all peculiarities for all difficulties; turns his picture into all manner of situation and light; looks at it from between his legs,—and all with the strictly critical view of discovering hidden defects, falsities of drawing, or imperfections. See to what perfection he carries his perception of surface, hair, silk, wool, rock, grass, foliage, distance, fog, mist, smoke! how he paints the glazed or watery eye!"

A writer in the London Daily News says: "Sir Edwin's method of composition was remarkably like Scott's, except in the point of the early rising of the latter. Landseer went late to bed, and rose very late, coming down to breakfast at noon; but he had been composing perhaps for hours. Scott declared that the most fertile moments for resources, in invention especially, were those between sleeping and waking, or rather before opening the eyes from sleep, while the brain was wide awake. This, much prolonged, was Landseer's time for composing his pictures. His conception once complete, nothing could exceed the rapidity of his execution."

In 1840, at the country house of Mr. William Wells, Landseer had his first violent illness associated with severe depression, to which attacks he was subject all the rest of his life. He went abroad for a time, travelling in France, Switzerland, and Austria, but he was constantly longing for his studio, where, he said, "his works were starving for him."

"Coming events cast their shadows before them," sometimes called "The Challenge," a vigorous stag bellowing his defiance to hunters or other animals of his kind; "Shoeing," which has been engraved many times, the mare, Old Betty, belonging to his friend Mr. Jacob Bell; and "The Otter Speared," a huntsman surrounded by yelping dogs, while he uplifts a poor otter on his spear, were all exhibited in 1844, and won great praise.

From Sir Edwin's sporting-scenes many persons gained the impression that he was a keen sportsman, which was not the case. Ewen Cameron, an old forest keeper of Glencoe, who for more than twenty-four years accompanied Landseer with the sketch-book and gun, tells how the highland gillies were annoyed when a magnificent stag came bounding toward them, and Sir Edwin hastily thrust his gun into their hands, saying, "Here! take! take this!" while he pulled out his book and began to sketch. They murmured greatly in Gaelic, but, says Cameron, "Sir Edwin must have had some Gaelic in him, for he was that angry for the rest of the day, it made them very careful of speaking Gaelic in his hearing after."

The companion pictures "Peace" and "War," painted in 1846—the former a beautiful scene on a cliff overlooking Dover harbor, the latter a ruined cottage with a dying horse and dead rider near the door—were sold to Mr. Vernon for seventy-five hundred dollars. The publishers of the engravings from these pictures paid Landseer fifteen thousand dollars for them. "The Stag at Bay," belonging to the Marquis of Breadalbane, one of Landseer's strongest pictures, appeared the same year.

In 1848, "A Random Shot," one of the artist's most pathetic pictures, was painted. Stephens thus describes it: "It is a snow piece, the scene high on the mountain, whose most distant ridges rise above the mist. The snow lies smooth; and for miles, so far as the eye can penetrate the vapor, there is nothing but snow, which covers, but does not hide, the shapes of the hilltops. A few footprints show that a doe has come hither, attracted, doubtless, by her knowledge of a pool of unfrozen water which would assuage her thirst. Some careless shooter, firing into a herd of deer, had hit the doe, whose fawn was with her, and, mortally wounded, she came to die; the poor fawn had followed. There the victim fell; there the innocent one strove, long after the mothers form was cold, to obtain milk where an unfailing source had been. The mother has fallen on her side; the long limbs, that once went so swiftly, are useless, and the last breath of her nostrils has melted the snow, so that, stained with her blood, the water trickled downwards until it froze again."

Monkhouse says, in his "Landseer Studies": "He painted dogs and deer as no man ever painted them before; he inspired one with a humor and both with a poetry beyond all parallel in art; he added to this a feeling for the grandeur and sublimity of nature, which gave to his pictures a charm and a sentiment which all can feel; he never painted anything false or ignoble, vulgar or unmanly; he won as an artist purely the affection and admiration of a whole people as scarcely any man, not a poet, or a soldier, or a statesman, or a philosopher, has ever won them before....

"Landseer may be said to have mastered other animals, but the deer mastered him. He raised dogs almost to the scale of humanity, but deer raised him to a level of higher being. His love for the deer may not have been so deep, but it was more elevating, less self-regarding, and it ended at last in stimulating his imagination to produce pictures deeper in thought and more awful in sentiment than any attempted by an animal painter before."
