posits of bitumen are found in the Timber Belt and Eagle Ford beds. 

 Thus, in the counties of Sabine, Shelby, Nacogdoches, San Augustine, 

 Anderson, Grimes, Travis, Bexar, and others, oil in small quantity has 

 been found. Most often, it is true, the quantity has been too small to 

 be of much economic importance, but in Nacogdoches County one of 

 the fields has had considerable development and the results are satis- 

 factory. Besides these deposits there are others in the Carboniferous 

 region, where small quantities of oil are secured in wells and springs 

 which appear to have a larger quantity of the lighter oils connected 

 with them. The only places at which oil is at present produced are 

 Nacogdoches and San Antonio. 



Nacogdoches Oil Wells. — In the vicinity of Chireno, Nacogdo- 

 ches County, a number of oil wells have been bored, many of which 

 became producers. A pipe line was run connecting the wells with the 

 railroad at Nacogdoches, and shipments of oil have been made from 

 time to time. This locality produces only a lubricating oil, but it has 

 the property (through absence of paraffine) of withstanding very severe 

 cold, and is therefore of high market value for railroad use where such 

 oils are needed. 



San Antonio Oil Well. — Mr. Geo. Dulnig, when boring on his 

 place for water, at a depth of three hundred feet struck petroleum, and 

 subsequently, in another boring at some distance from the first, came 

 upon it at two hundred and seventy feet. The flow is only about 

 twenty gallons a day, but is continuous and regular. The oil is a supe- 

 rior article for lubricating purposes. 



GAS. 



Another economic product accompanying these beds of bitumen and 

 oil is Natural Gas. Its existence has long been known in Shelby, Sa- 

 bine, and adjoining counties, and it was found in well boring in Wash- 

 ington County and elsewhere many years ago. Within the last two 

 years fresh borings have been made in the vicinity of Greenvine, in 

 Washington County, and the flow of gas found to be of considerable 

 amount It has been found near San Antonio at depths of from four 

 hundred to eight hundred feet, and also at Gordon and other places in 

 the Carboniferous area. No attempt has yet been made to bring it 

 into use, or even to fully test the character or extent of the fields thus 

 far determined
