Speaking afterwards of his work with this commission, Banneker referred to the unfailing kindness and courtesy of the distinguished company in which he found himself. One of his biographers says that the deportment of the mathematician during this engagement was such as to secure for him the respect and admiration of the commissioners. His striking superiority over all other men of his race whom they had met led them to disregard all prejudices of caste.[172] During the stay of the commissioners at their official quarters, Banneker was invited, of course, to eat at the same table with them just as he sat with them during the conferences. This invitation, however, he declined, and provision was then, at his request, made for serving his meals at a separate table but in the same dining room and at the same hour as the others were served. The reasons for Banneker's refusal to accept this invitation, however, are not so clear. Various of his biographers have attributed his action on this occasion to what they seemed pleased to term his "native modesty." Judging it at this distance from the time of its occurrence, it is perhaps difficult to understand fully his motive. But if we view it in the light of the consistent wisdom and high-mindedness that seemed to guide his whole life we can hope that his reasons for the self-imposed coventry on that occasion were sufficient unto himself, and that they fully excluded every element of servility. Banneker's work with this commission was undertaken while he was still engaged in astronomical investigation, and after his services in Washington were concluded he returned to his home and resumed his work on his almanacs, which regularly appeared until 1802. He was now living alone in the home left him by his parents, and performed for himself nearly all the domestic services required for his health and comfort. Still obliged to rely mainly upon his farm for his livelihood, he tried various expedients with different tenants to rid himself of the necessity for giving so much of his time to the farm. In these efforts he was wholly unsuccessful. He finally decided, therefore, to enter into such an arrangement in the disposition of his effects as would provide him an annuity, relieving himself of all anxiety for his maintenance and at the same time affording him the leisure he wanted for study. This he was enabled to do through a contract with one of the Ellicotts, by the terms of which his friend was to take the title to Banneker's property, making the latter an annual allowance of 12 pounds for a given period of time calculated by Banneker to be the span of years he could reasonably be expected to live. Banneker was to continue to occupy and use the property during his life, after which the possession was to go to Ellicott.[173] Banneker lived, however, eight years longer than he thought he would, but Ellicott faithfully lived up to this contract. This miscalculation
