His letters during the first half of 1790 betoken the same restless, unsatisfied spirit as those written towards the end of the previous year. Only we must be on our guard against interpreting his real state of mind too exclusively from his letters. For it seems to have been his habit when writing to his friends to take one mood of mind, (p. 117) which happened to be uppermost in him for the moment, and with which he knew that his correspondent sympathized, and to dwell on this so exclusively that for the moment it filled his whole mental horizon, and shut out every other thought. And not this only, which is the tendency of all ardent and impulsive natures, but we cannot altogether excuse Burns of at times half-consciously exaggerating these momentary moods, almost for certain stage effects which they produced. It is necessary, therefore, in estimating his real condition at any time, to set against the account, which he gives of himself in his letters, the evidence of other facts, such as the testimony of those who met him from time to time, and who have left some record of those interviews. This I shall now do for the first half of the year 1790, and shall place, over against his self-revelations, some observations which show how he at this time appeared to others. An intelligent man named William Clark, who had served Burns as a ploughman at Ellisland during the winter half-year of 1789-90, survived till 1838, and in his old age gave this account of his former master: "Burns kept two men and two women servants, but he invariably when at home took his meals with his wife and family in the little parlour." Clark thought he was as good a manager of land as most of the farmers in the neighbourhood. The farm of Ellisland was moderately rented, and was susceptible of much improvement, had improvement been then in repute. Burns sometimes visited the neighbouring farmers, and they returned the compliment; but that way of spending time was not so common then as now. No one thought that the poet and his writings would be so much noticed afterwards. He kept nine or ten milch (p. 118) cows, some young cattle, four horses, and several pet sheep: of the latter he was very fond. During the winter and spring-time, when not engaged in Excise business, "he sometimes held the plough for an hour or two for him (W. Clark), and was a fair workman. During seed-time, Burns might be frequently seen at an early hour in the fields with his sowing sheet; but as he was often called away on business, he did not sow the whole of his grain."
