ovoid buoy.
FIGURE 2 is a section on the line 2——2 of FIGURE 1. 45
FIGURE 3 is a section on the line 3—3 of FIGURE 1.
In the drawings like characters of reference designate

Describing ?rst the buoy of FIGURES 1 through 3,
the same will be seen to consist of a body collectively 50

in use surmounts the pole of minor amplitude 3.
The anchoring means associated with the buoy of FIG

having a gap 5 therebetween. Above the said gap is 55
positioned an open-ended sleeve 6. From a contempla

the axes of gap 5 and sleeve 6 may be said to lie in
parallel. Although in the accompanying FIGURE 5,
