If the equipment could be trusted, a solid mass was rising from the water on all sides of his ship.

The outer air swept in with greater authority, and the warm mass rose faster.

You'll get- The hot mass rose before them, its volcanic heat beating on their power.

As an object approaches the speed of light, its mass rises precipitously.

Its mass rose only six feet above the glitter of the ocean, so low it was impossible to see from ten miles away.

Then, as the mass rose still higher, two eyes gleamed bright in the darkness.

The dark bulging mass was rising higher and getting nearer.

The malignant mass beneath the mask of beauty now rose all but fully into view.

A mass of straw canvas sitting with its back to him rose.

Tall and clean over the turmoil rose the beautiful metallic mass.
