Penn.) fluvial, deltaic and marine clays and shales of north-central Texas. This work is part of a broad-scale investigation of upper Paleozoie clay and shale mineralogy in this area (Shover, ).

CISCO GROUP The upper portion of the Texas Pennsylvanian included in the Cisco group is characterized by its more clastic sediments, its thin but persistent limestones, and the presence of coal.

It includes all the beds between the Home Creek limestone of the Canyon and the lowermost beds containing Permian fossils. Sellards (Univ. Texas Bull. ) considered top of Home Creek as base of Cisco group, but lowered top of Cisco to top of Plummer and Moore's [] Camp Colorado limestone of Pueblo formation.

Bullard and Cuyler (Univ. Texas Bull. ) retained these boundaries but raised Graham-Thrifty boundary to top of Speck Mountain limestone.

A number of minerals containing copper, such as chalcocite, chalcopyrite, malachite, and azurite, occur in small deposits in Texas. They are found chiefly in the Llano uplift area of central Texas, in the Van Horn area of Culberson and Hudspeth counties in west Texas, and in a group of counties in north-central Texas.

On the Texas High Plains, a cement plant near Amarillo uses impure caliche as the chief raw material. Iron oxide, also a constituent of cement, is available from the iron ore deposits of East Texas and from smelter slag. Gypsum, added to the cement as a retarder, is found chiefly in North Central Texas, Central Texas, and the Trans-Pecos area.

These plants evolved into ferns, leafy plants, and a variety of tree-like shrubs that clothed the swamps and low lands. It was this late Paleozoic (Pennsylvanian Period) vegetation that gave rise to the coal deposits that extend much of the distance from Illinois eastward to Pennsylvania and in North-central Texas.

My first dog was named Cisco in honor of a popular television hero of the day, the Cisco Cisco Kid and his trusty sidekick Pancho rode the frontier fighting evil and injustice.

In his own way, Cisco did the same thing. Cisco was a pit bulldog, a breed with a tarnished reputation due to a number of unfortunate, sometimes deadly incidents.
