drainage district issued by the trustees of the internal improvement fund, 
November, 1911, gives the depths of the muck along the various canals and sur- 
vey routes. Along the Miami Branch Canal from north to south, the depth* of 
the muck is то, 4, 6.5, 5.5, 7, 6.5, 7, 3.8, 4, 6 feet. Along the North New River 
Canal, the determined muck depths are from Lake Okeechobee to the eastern 
edge of the Everglades 10, 2.5, 8, 7, 6.5, 5, 4, 3.5, 4.5, 7, 7, 6, 5 feet. The depths 
as measured along the West Palm Beach Canal in the extreme northeastern 
part of the Everglades region are 10, 8, 10, 3, 4 feet. The depths along an east- 
west line from Brown’s store to the eastern rim of the Everglades are 2, 4, 2.8 
4.5, 5, 2 feet. The depth of the muck along this line averages 4.5 feet (1.36 
meters). The top soil is a turf composed largely of saw-grass roots, except in the 
leads and shallow basins, where the saw-grass does not grow. Here the vegeta-

tion is more completely decayed and is so loose when saturated with water 
that one sinks to the bottom sand, or rock. The “leads,” filled with water and 
water-lilies alternating with saw-grass, give a deceptive undulating appearance 
as one looks across the expanse, though, as will be noted, the slope is gradual. 
The islands scattered over the Glades form an insignificant part of the whole— 
probably less than one-half of one per cent. of the entire saw-grass marsh. 
The people of South Florida speak of the “Upper” Glades and the 
“Lower” Glades, the former term being applied in general to the marsh be- 
tween Lake Okeechobee and the north line of Township 51, and the latter to 
the territory south of that line. There is but little peat on the rock in the
