VEGETATION OF SOUTH FLORIDA ied 
L. О. 32 Miles.—The saw-grass is everywhere. The presence of dredged 
rock here indicates the removal of a ridge of that material. 
L. O. 33 Miles.—Very little dredged rock lines the banks of the canal, 
hence the muck is deeper and formed in a deep depression. A clump of bushes 
was passed close to the canal on the right. 
L. O. 34 Miles.—Long lines of dredged rock indicate the section of 
another ridge. The slues become more frequent at the first bend of the canal. 
A clump of buttonbush, Cephalanthus occidentalis L., was noted. 
L. O. 35 Miles to L. O. 36 Miles.—Saw-grass prevails. An eagle was seen. 
L. O. 37 Miles (Ft. L. 24 Miles).—A slue was passed with saw-grass domi- 
nant. A low clump of trees was noted to the right of the canal. 
L. O. 39 Miles (Ft. L. 22 Miles).—Here was very low, wet saw-grass with 
lagoons and channel filled with water in which grew Nymphaea advena Soland. 
An occasional clump of bushes was noteworthy and a large hammock of low 
trees about a mile to the eastward. A great blue-heron was seen. 
L. О. go Miles (Ft. L. 21 Miles).—A large bald-eagle flew from the low, 
wet saw-grass marsh. A large amount of dredged rock material was piled 
high on both sides of the canal, indicating an Everglade ridge. Small clumps 
of trees were passed before the elbow of the canal was reached. Here two 
shrubs were common, viz., Cerothamnus (Myrica) ceriferus (L.) Small and 
Cephalanthus occidentalis L. 
L. O. 41 Miles (Ft. L. го Miles). The saw-grass is everywhere with inter- 
secting slues. Passed a clump of low trees on the left bank of the canal below 
the bend. A low ridge was found on the right side covered with clumps of 
bushes. 
L. O. 43 Miles (Ft. L. 18 Miles).—Here the saw-grass is broken by true 
hammocks, which become more frequent as we proceed southeastward until 
the sky-line seems to be a continuous line of low trees. Here are lagoons with 
yellow spatterdock. A hammock with several large trees was noted about 
half a mile away to the left. 
It may be stated at this point before we continue the field notes that the 
Lower Glades are characterized by frequent channels, lagoons and islands. 
The only map of the Everglades which shows these islands is the Military Map 
of the Peninsula of Florida, south of Tampa Bay, compiled from the Latest 
and Most Reliable Authorities by Lieut. J. C. Ives, and published in April, 
1856. East of the 3oth meridian are given from north to south, Saunders,
