Notes
on Do-It-Yourself Microscopy
Roger Baker
I have been fascinated by microscopes even
before I first made one from a fused glass
bead according to the directions in Scientific
American back in the 1950's. I improved
on the published design and used it to examine
pollen grains from the garden with the encouragement
of my grandfather, who was a doctor in the
era when microscopes were worshipped by
the medical profession. |

A
Visit to Alaska's Valley of 10,000 Smokes
Tim Dolan
Katmai is home to the Valley of Ten Thousand
Smokes. For years, this site of the
massive 1912 volcanic eruption was thought
to have been Mount Katmai, which is a
dormant volcano. It turns out that
the actual eruption occurred on the valley
floor. The vent is named Novarupta,
and it is now an unremarkable pumice-filled
crater.
