HOVEY: ARTESIAN WELL AT KEY WEST. TT 
very few discoid Orbitoides are present. Shells and casts of lamellibranchs 
numerous. Casts of gastropods. Spines and plates of echini. Some frag- 
ments of shells show the effects of boring organisms, Some bryozoa, both 
branching and incrusting. 
825 feet. — Color very light yellowish brown. Sample is finer grained 
than the last. Small amount of quartz sand, one rounded particle of which 
measured more than .5 mm. in length. Ovules present in considerable num- 
bers, In this and other cases the concentric structure is evident when the 
ovule is broken across. ‘The rock seems to have been somewhat compacted. 
More secondary calcite than usual. Many shells and casts of lamellibranchs 
and few of gastropods. Spines of echini and the facetted fragments. Annelid ? 
tubes. Foraminifera. Bryozoa. Some spicules of Gorgonia. A very few 
fragments of discoid Orbitoides. 
850 feet. — Color very light yellowish brown. Sample is a fine sand, nine 
tenths of which passed through the No, 40 mesh sieve, Trace of the quartz 
sand. Foraminifera of several genera abound. Some small fragments of coral, 
Branching and inerusting bryozoa of several genera were observed. Many 
shells and casts of minute lamellibranchs. Internal casts of very small gastro- 
pods. Spicules of Gorgontas numerous. Ovules also frequent. Spines of 
echini.  Orbitoides ? very scarce, but Cristellaria ?. Amphistegina 2 Orbitolites ? 
ete., numerous. 
875 feet. — Color very light yellowish brown, like the last. Mere trace of 
the quartz sand. Sample is nieagre in determinable organisms. Ovules not 
very numerous, Spicules of Gorgonia, spines of echini, and remains of lamelli- 
branchs are present. Some pieces of brown granular calcite. — Orbitoides not 
observed. 
900 feet. — Color, very light yellowish brown. Trace of quartz sand as in 
last. A few small fragments of loosely compacted rock. Foraminifera of sev- 
eral genera. Orbitoides in numbers appear. Some small bits of madrepore 
and other coral. Many shells and casts of small lamellibranehs. Gastropods 
not definitely recognized, Fragments of tests of echini. Nullipores? Spic- 
ules of Gorgonias. Ovules not very numerous, Some bits of brown granular 
calcite. 
925 fect. — Color very light yellowish brown. Many white particles. Faint 
trace of quartz sand. Ovules not numerous, but there are some pieces of 
očlite. Foraminifera abound among which Orbitoides are very numerous. 
Some few fragments of madrepore coral. Bits of echini occur, and опе litile 
fragment suggests the arm of an astrophyton. Remains of lamellibranchs are 
common, but those of gastropods are rare. Spicules of Gorgonias in numbers, 
Bryozoa not rare. Most of the determinable fragments are foraminifera. The 
whole sample looks like a moderately coarse beach sand rather than crushed 
rock. 
950 feet. — Color light yellowish brown. Texture same as preceding. Faint 
trace of quartz sand. The sample is a loose fine sand in which ovules are 
numerous. Foraminifera (Orbitoides, ete.) abound. Bits of madrepore сота!
