As the population grew, the markets were abundantly supplied. Great vessels packed with ice for sale in the town tied up at the wharves; open spaces devoted to gardens and outbuildings gave way to dwelling houses, and the town became more compact. Twelve or more servants were necessary for the maintenance of large establishments, varying in number according to the size of the family and the house. There was generally a butler, who acted as major-domo, a cook and kitchenmaid, body servants or valets for the head of the house and the young gentlemen, a ladies' maid, chambermaid, nurse and nursemaids, a coachman, stable boy, gardener, yard boy and laundress. During the first twenty years of the city's development, an entire block might contain not more than four homes. Each of these units functioned as a miniature and self-supporting estate, surrounded by flower and vegetable gardens and the usual outbuildings--necessaries, kitchen, dairy, ice house, smokehouse, fowl house, servant quarters and stable.

At the first frost the smokehouses were filled with hams and great sides of bacon. Game was plentiful, and during the season venison, duck, partridge, wild turkey, and woodcock appeared in market and graced the tables of the well-to-do. With tea from China and India, coffee from Brazil, oil and condiments from Spain, sugar and fruits from the West Indies, Alexandrians fared sumptuously. By 1770 Alexandria's tobacco trade had largely given way to wheat, and the local shipping merchants were finding their supplies farther and farther west in the valley of the Shenandoah. George Washington was one of the first planters on the upper Potomac to change his money crop from tobacco to wheat. He enlarged his mill and took advantage of the latest mechanical advances of his time. However successful he became as a wheat farmer, he never escaped the trials and grief caused by those middlemen, his agents. In 1767 he wrote a nine-page letter roundly berating Carlyle and Adam for the destruction of his bags and for delay in paying him for his wheat.
