Twain loved the paddlewheel steamboat and he loved the river. As a matter of fact, it was during his years on the river that he chose his pen name. Mark Twain was a frequent call of the leadsman. It meant that the water was 2 fathoms (12 feet) deep and indicated safe water. A leadline is used to determine water depth and the type of material which makes up the bottom or riverbed. A 30-foot-long line is attached to a pipe filled with lead, except for the bottom 2 inches.
1. Horticulture is a branch of plant agriculture and is both a science and an art. As an art, it incorporates the principles of design (as in landscaping). 2. Horticulture deals with intensively cultured and high-value crops.
They use pointed sticks, hoes, or other hand tools to make holes in the soil to plant their seeds, tubers, and cuttings. This is a labor intensive but not capital intensive form of farming. Pesticides and herbicides are not used by traditional subsistence horticulturalists.or instance, in North America, it takes about 2 pounds of oil to produce one pound of wheat. In contrast, horticulture is labor intensive but not capital intensive. Horticulture is only economically practical as long as the population density remains low and land for new fields is readily available.
