To his chagrin it was not there! He dived into both pockets of his jacket, then into his wide trousers, then under the breast of his waistcoat.

No.

The handkerchief was not to be found.

Alas! it had been left in the wagon! It was very annoying.
What else could he make use of?
Take off his jacket and hold it up?
It was not gay enough in colour.

It would not do.
Should he raise his hat upon the end of his gun?
That might be better, but still it would look too much like the human form, and Hendrik knew that all animals feared that.
A happy thought at length occurred to him.
