ABSTRACT:
This invention discloses a covering comprising a floating member shaped as a square loop, one pair of opposite portions of which are inflatable members, and a water-proof sheet having a nipple downwardly formed thereon, which is loosely stretched inside the square ring of the floating member and the peripheral edge of which is tightly connected with the same. The covering can float on the water and shield the water from scorching sunshine, killing frost, strong wind and acid rain. It is adaptable, therefore, to be used in nursery pool to protect the crops raised therein from damage by extraordinary weather.
