Percival's lack of means was in a way his own fault—or at least it was the result of his peculiar disposition which, in its sensitiveness to purely imaginary slights and its impossibility of concession or adaptation, worked constantly against his prosperity. His friends were faithful and long-suffering and often came to the rescue. In spite of his oddities there seems to have been a singular charm about the man like the charm of an unexpectedly original child. When the bane of an intense bashfulness was removed and he was alone with one or two intimates, his talk is said to have been delightful. He became absolutely absorbed in any topic in which he was interested and brought to bear upon it a wealth of allusion and comment of which few minds were capable.
As a poet he is now forgotten, yet it is a suggestive and significant fact that in 1828, when a project was in hand to publish a group picture of nine living American poets, Percival was to occupy the center of the stage, while such minor lights as Bryant, Irving and Halleck, with others, were to surround him.
But the fame he longed for and, with an almost childlike naïveté, claimed as his due, was short-lived. It barely touched him and passed him by. Yet he deserves remembrance, if only for his versatility. While it is chiefly as a poet that mention is made of him in encyclopedias and other books of reference, he was capable, but for his temperamental disabilities, of shining in many lines and in one pursuit other than poetry he has left a lasting memorial. He studied law, was admitted to the bar and never practiced. He served his medical apprenticeship under his good friend Dr. Eli Ives of New Haven, took his degree, practiced a little and, though he was always afterward known as "Doctor," abandoned the profession—except that later in life he was post surgeon at Boston till his abhorrence of examining recruits compelled him to relinquish the work. At one time he thought of entering the ministry and he was always an authority on theology and dogma. He gave up his appointment as a professor of chemistry at the Military Academy at West Point because in going to his quarters he had to use the same hallway with other officers. He was a learned botanist and a linguist of rare attainments. In 1827 he carried through successfully the immense task of correcting the proofs and supervising the publication of Webster's unabridged dictionary—and seems to have been happier in this work of enormous detail than at any other time of his life.
But it was as a geologist that his most valuable practical work was done. His "Report on the Geology of Connecticut," published in 1842, was the result of five years of arduous labor and is a sufficient monument for any man.
"While engaged in this survey," he wrote, "I can confidently say that I have been laborious and diligent. While traveling, it was my practice to rise early, in the longer days generally at dawn; in the shorter generally I got my breakfast and was on my way by daybreak, I continued, scarcely with any relaxation, as long as I had daylight and then was generally obliged to sit up till midnight, not unfrequently till one o'clock A. M. in order to complete my notes and arrange my specimens. This was continued, not only week after week, but month after month, almost without cessation."
Under the law Percival could not be paid till his report had been approved by the governor. It is characteristic of the whimsical geologist that he refused to submit to this approval by one whom he considered incompetent to pass upon his labors and it was only by the ruse of a friend who got possession of the report and presented it to the governor, who at once approved it, that Percival secured his pay.
This work brought Percival a high reputation as a geologist. He was engaged by the American Mining Company to investigate the lead deposits in Wisconsin and this in turn resulted in his employment by that state to make a geological survey similar to that of Connecticut. He had made his first report and was engaged upon his second when he became ill and in May, 1856, he died and was buried in Hazel Green, Wisconsin. "Eminent as a Poet," runs his epitaph, "rarely accomplished as a Linguist, learned and acute in Science, a Man without Guile."
During his employment in Wisconsin his friends had bought a lot and built a house for him in New Haven. It was a queer structure, built after the poet's own plans, with the entrance at the rear, blind windows at the front, and of only one story in height. He was looking forward to spending here his last years, close to his college, with his few intimate friends, surrounded by his books. During an interval in his Wisconsin employment he came to New Haven to inspect his future home and is said to have broken down completely as he was compelled to leave by the duty that called him westward.
He was a strange creature, impossible to get along with, handicapped by an over-sensitiveness that led him into resentments that often held the implication of ingratitude, and with a constant grudge against the world. He should have been endowed and relieved of all the detail of life. Even then it is doubtful if he would have produced great poetry, unless he had been rigorously trained by some dominant master to condense, revise and work over again and again his diffuse, sentimental and dreamy verses. A few of them retained for a time a certain vogue and then gradually passed into oblivion. Perhaps the two that were longest remembered were "To Seneca Lake" and "The Coral Grove." It is an odd thing, but some selections from a boyish effort entitled "Seasons of New England," hitherto generally cited as evidence of his youthful absurdities, would make excellent examples of the free verse that nowadays is taken so seriously. In this respect, at least, he was ahead of his time.
In his review of the "Life and Letters" Lowell seems rather dogmatic and intolerant, but with his inevitable insight and art of statement he crystalizes into one sentence the whole trouble with Percival. "He appears," writes Lowell, "as striking an example as could be found of the poetic temperament unballasted with those less obvious qualities which make the poetic faculty."
