More originals of gag cartoons I've found here and there on the internet.
An editor often bought cartoons without captions and added one later upon publication. Here the seller acquired originals without captions so added one of their own.
Another says “I'm not losing a moment, Dad. I was voted most likely to succeed!”
or “Gosh, Frank, how far do they really go on this geology bit?”
The “freshly seeded” may have been added by an editor as well.
