It was early September, and the evenings were growing cool.

The night was growing cool as the train reached the coast.

It was growing cool, even cold, with the departure of the sun.

The room had grown dark and cool with the setting of the sun.

Come in and shut the door, for it grows cool when the sun goes down.

The sun had set and the air was growing cool.

The grass grew cool about me and turned soft in color.

The desert here was high enough so that the night had grown quite cool.

Toward the evening it grew cool, and darkness came suddenly.

Fortunately it was soon over and the air began to grow cool again.
