His poetry might be bad or good; he no doubt wanted a lyric facility and technical skill; but he had the source of poetry in his spiritual perception. He was a good reader and critic, and his judgment on poetry was to the ground of it. He could not be deceived as to the presence or absence of the poetic element in any composition, and his thirst for this made him negligent and perhaps scornful of superficial graces. He would pass by many delicate rhythms, but he would have detected every live stanza or line in a volume, and knew very well where to find an equal poetic charm in prose. He was so enamored of the spiritual beauty that he held all actual written poems in very light esteem in the comparison. He admired Aeschylus and Pindar; but, when some one was commending them, he said that "Aeschylus and the Greeks, in describing Apollo and Orpheus, had given no song, or no good one. They ought not to have moved trees, but to have chanted to the gods such a hymn as would have sung all their old ideas out of their heads, and new ones in." His own verses are often rude and defective. The gold does not yet run pure, is drossy and crude. The thyme and marjoram are not yet honey. But if he want lyric fineness and technical merits, if he have not the poetic temperament, he never lacks the causal thought, that his genius was better than his talent. He knew the worth of the Imagination for the uplifting and consolation of human life, and liked to throw every thought into a symbol. The fact you tell is of no value, but only the impression. For this reason his presence was poetic, always piqued the curiosity to know more deeply the secrets of his mind. He had many reserves, an unwillingness to exhibit to profane eyes what was still sacred in his own, and knew well how to throw a poetic veil over his experience. All readers of "Walden" will remember his mythical record of his disappointments:-- "I long ago lost a hound, a bay horse, and a turtle-dove, and am still on their trail. Many are the travellers I have spoken concerning them, describing their tracks, and what calls they answered to. I have met one or two who had heard the hound, and the tramp of the horse, and even seen the dove disappear behind a cloud; and they seemed as anxious to recover them as if they had lost them themselves." [_Walden_, p. 20.] His riddles were worth the reading, and I confide, that, if at any time I do not understand the expression, it is yet just. Such was the wealth of his truth that it was not worth his while to use words in vain. His poem entitled "Sympathy" reveals the tenderness under that triple steel of stoicism, and the intellectual subtilty it could animate. His classic poem on "Smoke" suggests Simonides, but is better than any poem of Simonides. His biography is in his verses. His habitual thought makes all his poetry a hymn to the Cause of causes,
