Translation of Chinese Scroll and Seal
The seal pointing to the artist name says 任可澄. In particular, you're very unlikely to find out the last character 「澄」 through a simple search:

The right hand side of the character 「澄」 in the seal is actually 「⿱豆廾」, which is a variant shape of 「登」 sometimes appearing in bronze inscriptions.
「澄」 is not a character appearing in bronze inscriptions, so the character in the seal is a modern character hypothetically back-projected to a bronze inscription form.
