Found it was done while drying them to near the fire

Angles and dips of the magnetic kind

Dry bulbs and wet were ever on his mind

Strong in debate on theories scientific

Passed many a weary hour on the Pacific

Dr. Vandyke the foothills oft would skirt

Oe’r turning stones and delving in the dirt

Beetles and bugs, all things that fly and crawl

Were his delight, and well he knew them all

If one were ill, or hovering near the Brink
