The fourth largest employer of workers engaged in manufacturing is the lumber and lumber products industry. In the latter part of the Nineteenth Century and the early Twentieth Century, this industry had the greatest number of employees in the manufacturing field. Gradually its importance declined until the 1930's when it increased rapidly as the demand for lumber production increased until, at present, it has reached fourth place. Approximately 77% of Virginia's total lumber industry employees is found in the sawmills and planing mills, especially in mills located in Franklin, Petersburg, Norfolk and Richmond. Whereas the synthetic fibers mentioned previously are manufactured primarily in seven large plants with numerous employees per plant, the lumber industry in Virginia consists of approximately 1700 establishments--only approximately 200 of which employ at least twenty employees. Veneer mills, excelsior mills, mill-work plants, plywood plants and companies which make fruit and vegetable baskets, boxes and crates also furnish diverse types of wood products for the Virginia lumber industry. The fifth largest employer of workers engaged in manufacturing is the apparel industry. Approximately one-half of all such employees are engaged in making men's and boys' clothing: suits, coats and overcoats are made in large quantities in Richmond, Staunton and Norfolk; shirts, pajamas and underwear at Danville, Radford, Lynchburg and Marion; trousers, overalls and sports jackets at Martinsville, Richmond and Staunton. Women's and misses' dresses are manufactured at Roanoke, maids' and nurses' uniforms and sports jackets at Lynchburg, lingerie at Staunton and Roanoke, gloves at Lynchburg, children's and infants' dresses and play clothes at Newport News and Shenandoah. Supplementary textile products include sheets and pillow cases (Danville), towels (Fieldale), hassocks, canvas awnings and automobile seat covers (Richmond). The sixth largest employer of workers engaged in manufacturing is the transportation equipment industry. Most of this employment is found in shipbuilding at the Hampton Roads area where aircraft carriers, atomic submarines, ocean liners--such as the "Constitution" and the "United States"--and numerous smaller vessels are constructed. Other employees of this industry work in numerous truck and bus body companies scattered throughout the state, in railroad equipment companies--for example, brake shoes (Roanoke); railroad bearings (Petersburg) and in a wagon company (Lynchburg).
