An interesting fact about Alabama's agriculture is that since 1958 livestock sales have brought more income than crops. Cattle are raised chiefly in the Black Belt and hogs in the Wire Grass area. Poultry raising is concen­trated north of Birmingham. Dairying is carried on throughout the state.

Mining. Alabama is well-known for its production of coal, cement, and limestone. A number of other' minerals are produced in varying quantities including petroleum, iron ore, clays and shale, mica, sand and gravel, bauxite, gold, silver, and manganese. Marble from Alabama's quarries is sold throughout the United States.

The first producing oil well began operating near Gilbertown, in Choctaw County, in 1944. Later, oil was found in Escambia County and near Citronelle, in Mobile County. There arc more than 200 producing wells in southwestern Alabama. In the northwest a large natural gas field is being developed.

Transportation and Communication

Waterways, railroads, highways, and airways connect Alabama to other parts of tlic nation. The port of Mobile connects the state to the seaports of the world.

Waterways. Alabama has the finest river system in the nation. The U.S. Corps of Engineers classifies large portions of its rivers as suitable for navigation. Millions of dollars have been spent to develop the harbor and build docks at Mobile, to widen and deepen the channels of the rivers, and to build public docks along the waterways.

The Black Warrior and Tombigbee waterway extends all the way from the port of Mobile to Jefferson and Walker counties. This waterway carries great quantities of limestone as well as millions of tons of cargo for the industries of Birmingham and other cities along the rivers. The Alabama River provides water transportation between Mobile and the capital city, Montgomery. The Tennessee River is the main water route of northern Alabama. The Chattahoochee waterway, on the east border of the state, serves the cities of Columbia, Eufaula, and Phenix City.

Railroads and Highways. Alabama was among the pioneers in railroad building. Its first railway, between Decatur and Muscle Shoals, was completed in 1832. Today Ala­bama's railroads are used largely for freight. Hubs of state, federal, and interstate highway systems are Birmingham and Montgomery.

Airlines. Several airlines provide com­mercial flights to cities in different parts of the state. Frequent daily schedules are avail­able from major centers. Most of the inter­state traffic uses the airports at Birmingham, Huntsville, and Mobile. Alabama's system of local airfields, with paved and lighted run­ways for smaller planes, is considered to be among the best in the nation.

Newspapers, Radio, and Television. Almost every city has its own local newspaper. More than 100 newspapers are published in the state, but only about 20 are dailies. Among the more influential daily newspapers are the Alabama Journal and the Montgomery Advertiser, both published at Montgomery, and the Birmingham News. The Mobile Press-Register, originally the Gazette, is one of the oldest newspapers in the state. It was founded in 1815.

Birmingham had the state's first licensed radio station, WBRC, in 1925, and the first television stations, WABT and WBRC-TV, both in 1949. In 1955 Alabama began operating one of the first state-owned educational television networks (ETV) in the nation. Stations of this network are capable of reaching almost all the people in the state.

EDUCATION

Alabama is proud of its natural resources and its industrial development in recent years. State and community leaders also recognize the importance of developing its educational and cultural institutions.

Schools and Colleges

The first teachers in Alabama were probably French and Spanish priests who gave instruction to the Indians. In 1799 a New England cotton merchant, John Pierce, opened a school for the children of wealthy settlers in the Mobile Bay area. It was the kind of pioneer school known as a blab .school because the pupils studied by repeating their lessons aloud.

When Alabama became a state in 1819, an attempt was made to establish a system of public schools. The attempt failed, as did others in later years, largely because of a lack of money. Private schools sprang up to edu­cate the children of parents who could afford to pay. It was not until after the Civil War that the state was able to make progress toward establishing its present system of public elementary schools, high schools, and colleges.

Alabama has more than 50 institutions of higher education. About half of these are 2-year institutions, mainly state-supported junior or community colleges. The others are universities and senior colleges.

The University of Alabama at Tuscaloosa (post office address, University) is Alabama's oldest college. It was established by the legislature in 1820. Other state-supported universities are located at Auburn, Birmingham, Florence, Huntsville, Jacksonville, Livingston, Mobile, Montcvallo, Montgomery, Normal, and Troy. Tuskegcc Institute, the famous school established by Booker T. Washington in 1881, is partly supported by the state.
