In another epistle Campbell threatens to "send a formal message to the kind nymphs of Parnassus, telling them that, whereas Hamilton Paul, their favourite and admired laureate of the north, has been heard to express his admiration of certain nymphs in a certain place; and that the said Hamilton Paul has ungratefully and feloniously neglected to speak with due reverence of the ladies of Helicon; that said Hamilton Paul shall be deprived of all aid in future from these goddesses, and be sent to draw his inspiration from the dry fountain of earthly beauty; and that, furthermore, all the favours taken from the said Hamilton Paul shall accrue to the informer and petitioner!"

After two years' residence in the Highlands, both the poets returned to Glasgow to resume their academical studies: Campbell to qualify himself as a man of letters, and Paul to prepare for the ministry of the Scottish Church. "It would have been impossible, even during the last years of their college life," writes Mr Deans,[72] "to have predicted which of the two students would ultimately arrive at the greatest eminence. They were both excellent classical scholars; they were both ingenious poets; and Campbell does not appear to have surpassed his companion either in his original pieces or his translations; they both exhibited great versatility of talent; they were both playful and witty; and seem to have been possessed of great facilities in sport. During his latter years, when detailing the history of those joyous days, Mr Paul dwelt on them with peculiar delight, and seemed animated with youthful emotion when recalling the curious frolics and innocent and singular adventures in which Campbell and he had performed a principal part."

While resident at Inverary, Mr Paul composed several poems, which were much approved by his correspondent. Among these, a ballad entitled "The Maid of Inverary," in honour of Lady Charlotte Campbell, afterwards Lady Bury, was set to music, and made the subject of elaborate criticism. On his return to the university, he composed with redoubled ardour, contributing verses on every variety of topic to the newspapers and periodicals. Several of his pieces, attracting the notice of some of the professors, received their warm commendation.

Obtaining licence to preach, the poet returned to his native county. During a probation of thirteen years, he was assistant to six parish ministers, and tutor in five different families. He became joint-proprietor and editor of the Ayr Advertiser, which he conducted for a period of three years. At Ayr he was a member of every literary circle; was connected with every club; chaplain to every society; a speaker at every meeting; the poet of every curious occurrence; and the welcome guest at every table. Besides editing his newspaper, he gave private instructions in languages, and preached on Sabbath. His metrical productions became widely known, and his songs were sung at the cottage hearths of the district. His presence at the social meeting was the sure indication of a prevalent good humour.

In 1813, Mr Paul attained the summit of his professional ambition; he was ordained to the pastoral office in the united parishes of Broughton, Glenholm, and Kilbucho, in Peeblesshire. Amidst due attention to his clerical duties, he still found leisure to engage in literary pursuits, and continued to contribute to the public journals both in prose and poetry. Of the poet Burns he was an enthusiastic admirer; he was laureate of the "Burns' Allowa' Club," and of the Glasgow Ayrshire Friendly Society, whose annual meetings were held on the Bard's anniversary; and the odes which he composed for these annual assemblages attracted wide and warm admiration. He therefore recommended himself as a suitable editor of the works of Burns, when a new edition was contemplated by Messrs Wilson and M'Cormick, booksellers in Ayr. In the performance of his editorial task, he was led, in an attempt to palliate the immoralities of Burns, to make some indiscreet allusions respecting his own clerical brethren; for this imprudence he narrowly escaped censure from the ecclesiastical courts. His memoir, though commended in Blackwood's Magazine, conducted by Professor Wilson, was severely censured by Dr Andrew Thomson in the Christian Instructor.

The pastoral parish of Broughton was in many respects suited for a person of Hamilton Paul's peculiar temperament and habits; in a more conspicuous position his talents might have shone with more brilliancy; but, after the burst of enthusiasm in his youth was past, he loved seclusion, and modestly sought the shade. No man was less conscious of his powers, or attached less value to his literary performances.[73] Of his numerous poetical compositions each was the work of a sitting, or had been uttered impromptu; and, unless secured by a friend, they were commonly laid aside never to be recollected. As a clergyman, he retained, during a lengthened incumbency, the respect and affection of his flock, chiefly, it may be remarked, from the acceptability of his private services, and the warmth and kindliness of his dispositions. His pulpit discourses were elegantly composed, and largely impressed with originality and learning; but were somewhat imperfectly pervaded with those clear and evangelical views of Divine truth which are best calculated to edify a Christian audience. In private society, he was universally beloved. "His society," writes Mr Deans, "was courted by the rich and the poor, the learned and the unlearned. In every company he was alike kind, affable, and unostentatious; as a companion, he was the most engaging of men; he was the best story-teller of his day." His power of humour was unbounded; he had a joke for every occasion, a bon-mot for every adventure. He had eminent power of satire when he chose to wield it; but he generally blended the complimentary with the pungent, and lessened the keenness of censure by the good-humour of its utterance. His anecdotes are familiar over a wide district, and many of his witty sayings have become proverbial. He was abundantly hospitable, and had even suffered embarrassments from its injudicious exercise; still he was always able, as he used to say—

"To invite the wanderer to the gate,
And spread the couch of rest."

It was his earnest desire that he might live to pay his liabilities, and he was spared to accomplish the wish. He died on the 28th of February 1854, in the 81st year of his age.

In appearance, Hamilton Paul presented a handsome person, tall and erect; his countenance was regular and pleasant; and his eyes, which were partially concealed by overhanging eye-lashes, beamed with humour and intelligence. In conversation he particularly excelled, evincing on every topic the fruits of extensive reading and reflection. He was readily moved by the pathetic; at the most joyous hour, a melancholy incident would move him into tears. The tenderness of his heart was frequently imparted to his verses, which are uniformly distinguished for smoothness and simplicity.
