HOVEY: ARTESIAN WELL AT KEY WEST, 79 
The sample is a coarse caleareous sand (gravel it might be Шей) with many 
recognizable fragments in it, and not much of it passed through the sieve. 
Some pieces of compact limestone. No ovules were observed. Foraminifera 
not as numerous as in last. Bits of madrepores very numerous. Spines and 
plates of echini are scarce. Bryozoa are common, and lamellibranch remains 
are very abundant. А few of the fragments indicate that some of the lamelli- 
branehs were quite large. A few gastropods were noted. 
1,150 feet. — Color light brownish gray. Very slight trace of the quartz 
sand. Тһе sample is a coarse 'aleareous gravel (comminuted rock) like the 
last. Foraminifera of several genera are numerous. Bits of madrepores are 
common. Some spines and plates of echini were observed. Lamellibranch 
remains very numerous. Jastropod shells not uncommon, and some genera 
noted not seen before. Ovules appear to be absent. 
1,175 feet. — Color light brownish gray, like that of preceding. Very slight 
trace of the quartz sand. The sample consists largely of comminuted rock, but 
there are many rounded sand grains in it and a very few ovules; the latter 
were determined by their concentric structure, Foraminifera are numerous, 
but bits of coral (madrepores) are less abundant. А few spines and plates of 
echini were noted. Bryozoa numerous. Lamellibranchs ave very abundant. 
Jastropods more common than usual. 
1,200 feet, — Color light brownish gray. The limpid quartz sand is present 
as usual in very small amount. Sample seems to be a very finely comminuted 
rock, as it is made up for the most part of angular fragments. It is much finer 
grained than the last two, and there are fewer determinable fragments. No 
ovules. Foraminifera are common, and minute bits of coral (7) abound. Ке- 
mains of echini are very scarce. Bryozoa rather common. Lamellibranch 
remains are very numerous, but there are very few gastropods. 
1,225 feet. — Very light brownish gray. The quartz sand js present as a 
mere trace. The same is a very fine calcareous sand, most of the grains of 
which are rounded. Мо ovules. More than nine tenths passed through the 
sieve, and the rest is not very course. There are a few angular bits of lime- 
stone in the residue. Not mueh is determinable, but I noted a few foraminif- 
era, many fragments of co ral, some lamellibranchs, and a few gastropods (7). 
1,950 feet, — Color very light brownish gray with many white particles. The 
amount of quartz sand is greater than it has been for 350 feet. The sample 
consists of a very fine grained calcareous sand, with comparatively few coarse 
particles in it, but in the latter are some angular bits of rock. Among the 
coarser partieles are many foraminifera and bits of coral. Echini not noted. 
Bryozoa doubtiully recognized. Lamellibranchs, as well as gastropods, seem 
to be scarce. Some ovules and a few small bits of oólite were observed. 
1,975 feet. —- Color light brownish gray. Quartz sand present in small 
amount, The percentage of coarser material is greater than in the last two, 
and one can see in it bits of porous as well as compact limestone. Sample, 
aside from organic remains, consists largely of rounded grains. Ovules were 
observed, but they are very scarce (and may have come from 1,250 feet ?).
