PRELIMINARY REPORT ON PEAT. 
303 
deposits somewhat similar to this are cultivated in Hillsborough 
County. 
31, 32. For description of this locality see pages 279-281. 
34. A good crop of corn was growing on this peat deposit. 
Peat black and fine on top (probably on account of being aerated 
and cultivated for several years), but coarser and dark brown 
a few feet below the surface. 
35. For description of this locality see pages 281-282. 
36. This bay was only about 50 feet in diameter, but there are 
plenty of larger ones, probably with just as good peat, in the 
immediate vicinity, and close to the railroad . 
37. See illustration, fig. 22. A very good deposit for local 
use. 
38. Similar to the preceding, a little better if anything, for 
it is drier and firmer, also nearer town. 
41. Several hundred acres of excellent peat, right on a railroad. 
42. Several hundred acres of coarse fibrous peat, right on a 
railroads, but remote from habitations. (These last two localities 
are illustrated on plate 27.) 
MISCELLANEOUS ANALYSERS'. 
A few analyses of Florida peat have been obtained from 
other sources, as follows: 
i. Small peat prairie about two miles northwest of Orlando, 
Orange County. The peat here seems to be at least 15 feet 
deep, and a few years ago a good deal of it was excavated to 
a depth of about 8 feet, put through a briquetting machine on the 
spot, and when dry taken to town and used for fuel in the light, 
water and ice plant. Analyses taken from U. S. Geol. Surv. 
Mineral Resources for 1905, p. 1321, and Bulletin 290, p. 77. 
In these publications the fixed carbon and volatile matter were given 
only for air-dry peat, but I have re-computed these two factors on 
a water-free basis, so that they can be compared with the table 
above. 
2 to 5. Marsh at confluence of Davis and Julington Creeks, 
Duval County, already described. Samples collected by Robert 
Ranson in May, 1908, from various depths (of which the records 
are not now available), analyzed by the U. S. Geological Survey, 
and results communicated to the writer by Dr. Chas. A. Davis. 
6. Average of 26 samples from various points in the vicinity 
of the St. Johns River, analyzed for Robert Ranson, and com¬ 
municated by him. His figures were for air-dry peat, but I have 
re-computed them on a water-free basis, except the fuel value.
