It had just begun to snow again and the mists were growing thicker.

Darkness soon surrounded them, and the mist grew even thicker, if that were possible.

The mist around the bed grew thicker and darker blue.

Soon the mist grew thicker and he could see only a few feet in front of him.

Meanwhile a mist was growing dense and soft upon the quiet waters.

The mist and the hail grew thick enough to turn day to twilight.

The black mist in front of him grew thicker.

But the mist grew thinner as the sun shone on it.
