Agriculture in 17th-Century Maryland
When Leonard Calvert, acting on behalf of his brother Cecil, second Lord Baltimore, arrived in Maryland in 1634, Virginia had been a going concern for more than a quarter-century, & other English-speaking colonies had begun in Massachusetts, Bermuda & the Bahamas, & several Caribbean islands. Those developments made it somewhat easier to begin farming in the northern Chesapeake, where planters could rely on the Virginians for plant & animal stock & have existing markets in which to sell.
Upon arriving in Maryland, Father Andrew White noted the native grapes & several types of small fruit, but also wrote that peaches grew abundantly. Since peaches were of Old World origin, Father White may have seen these fruits on Kent Island, where William Claiborne had begun raising hogs around 1628, & might have introduced peaches to feed them.
Unsure how the Virginians would receive them, Calvert's colonists bought maize seed in Barbados before continuing to the Chesapeake. The chief feature of this "corn" ("corn" meant the principal cereal crop of a region; thus English "corn" was wheat) was its ease of planting-in mounds dispersed over roughly cleared land rather than hand-broadcast upon a cleared field, like wheat.
A heavy hoe was the only implement necessary to grow Indian corn. What little evidence exists suggests that the Indians planted corn about three feet between mounds in all directions (i.e. one mound to 9 square feet) & the colonists followed the same practice.
Presumably, someone (Indian or English) tried to space the plants more closely, but if so, this probably introduced a bacterial rot of the stalk, just above the soil line, that inhibited denser planting until the first scientific hybrids in the twentieth century. After three seasons, in 1637, Maryland's leaders considered enacting a "two-acre" rule as Virginia had done, requiring two acres of corn to be planted for every acre of tobacco. This failed on its first suggestion but became official policy in 1638/9 with "An act for planting of corne," which passed again in 1640, 1642, 1649, & so on, leaving the impression that self-sufficiency was not something farmers took very seriously. No doubt supposing they could always get victuals such as corn for bread from some other source-Indians, Virginians, or West Indians-Marylanders wanted to devote their energies to raising the money crop, tobacco.
More than a century before Maryland's founding, the Spanish cultivated the Mayans' drug plant, tobacco, in the West Indies. It was grown in France by the mid-1550s, & in China, Japan, & South Africa before the settlement of Virginia. Farmers in England grew tobacco legally until 1619 (& illegally afterward), when a law aimed at generating import duties gave the Virginia Company a virtual monopoly of the market. By 1634, Virginia had been a royal colony for a decade, & nothing prohibited Maryland farmers from entering the profitable tobacco trade from their start.
A teaspoon of tobacco seeds was enough to plant six acres. The seeds were started in a seedbed, then the seedlings transplanted to mounds spaced like those for corn over a roughly cleared field. Both corn & tobacco required similar handling-hoeing down weeds, picking off bugs, chopping the stalk at harvest time & allowing the tobacco leaves or corn kernels to dry. The next year, the planter simply chose another spot, a few feet away, & repeated the routine. After a few seasons, however, planters would have noticed their plants were less robust than at first, & generally, that the plants produced less per field. This decline led farmers to think that the crop had depleted the soil of nutrients, leading to its "exhaustion."
Farmers responded by letting "old fields" "rest" for up to twenty years. In order to keep producing tobacco, growers moved to new fields, thus using up more & more land & deserting exhausted fields. Over decades, this practice made for a forlorn-looking landscape & tagged tobacco growers with the reputation of being slovenly & unskilled farmers at best, & rapacious at worst. "Soil exhaustion," actually caused by microbes, also figured in arguments over slavery & for agricultural reform.
For most of the 17th century, tobacco held complete sway over Maryland agriculture. When prices were high, little else mattered; when prices fell, even ruinously, growers simply awaited a reversal of fortune. Rather than building fences, improving meadows, & storing up winter feed, as good livestockmen knew to do, tobacco farmers simply let their animals run in the woods to fend for themselves, or, at most, grew an orchard for their scrounging. Because nothing else earned as much money per acre as tobacco, the "sotweed" remained the mainstay of Maryland agriculture for better & worse. The first black slaves arrived in Virginia in 1619, & in 1660, only 3% of the colonists were black. Until the early-mid 1700’s, white convicts & voluntarily indentured white people formed a greater part of the tobacco workforce. And until something else offered a similar opportunity for wealth, or even a living, tobacco dominated Maryland's agricultural practices & economy.
The Problem with Tobacco: What did we know & when did we know it?
As early as the 1600’s a number of physicians began to note that heavy smoking of tobacco in pipes appeared to be associated with an increased risk of oral cancers. The German surgeon Samuel Thomas von Smmerring (1755-1830) voiced concern over the apparent link between lip cancer & pipe smoking in 1795. Others had made similar observations including the apparent correlation between the location of cancerous tumors of the lip & mouth & the side of the mouth that smokers were accustomed to holding their pipe.
English surgeon Sir Percivall Pott (1714–1788) began to investigate cancer in the mid 1700’s & discovered that chimney sweeps had an increased rate of scrotal cancer. His investigation into other cancers in chimney sweeps & other professions indicated that cancer could have environmental triggers. Pott concluded that soot & smoke were directly linked to an increase in cancer risk & as such, he became concerned over the health effects of smoking tobacco. Although Pott was the first to formally investigate the association of soot & smoke with cancer, the fact that chimney sweeps appeared to be at higher risk was noted as early as 1602.
In 1761, English physician John Hill (c 1716-1775), who was often called a quack doctor & quarreled with the Royal Society made the first formal investigation into tobacco usage & cancer. He noted the increased incidence of oral & nasal cancer in both tobacco smokers & users of snuff. In his report Cautions Against the Immoderate Use of Snuff he stated “snuff is able to produce swellings & excrescences in the nose, “and he believed these to be cancerous."
