THE ARTESIAN WATER SUPPLY OF EASTERN FLORIDA. MIDDLEBURG. Middleburg lies in the north-central portion of Clay County, just at the point where Black Creek divides, forming the north and south forks. There are several flowing wells in the vicinity of Middleburg. The wells vary in depth from 355 to 498 feet. The 498 foot well is owned by George A. Chalker and was drilled in 1907 by D. C. Stafford. The well is six inches in diameter at the top and one and a quarter inches at the bottom. The pressure of this well as indicated by the pressure gauge January IO, 19IO, was 18.5 pounds, or a pressure sufficient to cause the water to rise 42.7 feet above the surface. The elevation of the well is approximately 24 feet above the level of the water in Black Creek; thus with the head of 42.7 feet above the surface would give the well a total head of 67.7 feet above the water in Black Creek. The temperature of the water at the point of overflow was reported as 720 F. The first rock of which note was made was at a depth of 68 feet. The well of ,. C. Howard, two miles northeast of Middleburg. has a depth of 490 feet. The well was bored by D. C. Stafford in 1907, is cased 8o feet and is four inches in diameter. The pressure of this well could not be taken, but it is reported to have a head of 21 feet above the surface. Another well two and a half miles northwest of Middleburg was sunk by D. C. Stafford for Messrs. Long and Buddington in 1907. The exact depth of this well could not be obtained, but it was reported to have a depth of about 370 feet. The well flows and gives an abundant supply of water but measurement of the head could not be made. In addition to the above wells is one eight and one-half miles northwest of Middleburg, or six miles southeast of Maxville, on the west bank of Yellow Water Creek, a tributary of the north fork of Black Creek. This well is located in the northwest part of the northwest quarter of the southwest quarter of Section 17, Township 4, Range 24 east. It is owned by Messrs. Long and Buddington, and is said to be 370 feet deep. It is a three-inch well and was drilled in i9o7 by D. C. Stafford. The head of this well is reported to be 30 feet above the surface and the first flow encountered was at a depth of 44 feet in a stratum of black pebbles, PEORIA. A deep well was put down by Mr. Joseph Doyle at Peoria. This well was drilled to a total depth of 498 feet. The water rises to the surface giving a slight flow. The well is located about one-half 159
