Truly a classic of living, intelligent nature study.
I'm quite pleased to have actually finished this book after slowly plugging away at it for almost six years, alternately by myself and aloud to the kids for school. Most of it I read on the Kindle version, which I bought to avoid heaving the hulking tome. Near the end, I was able to get some of the lovely separate volumes published by Living Book Press, and they are just the right size, with updated color photos added to the classic text.
I often found myself in awe of the way Comstock blended careful scientific detail with beautiful, captivating language. Even though there are tiny bits outdated here and there, it is quite solid science, and the outdated parts often serve to teach history (such as how metereology was done before GPS and the internet).
From the last chapter on the moon:
"Imagine this barren, dead world, chained to our earth by links forged from unbreakable gravity, with never a breath of air, a drop of rain or flake of snow, with no streams, nor seas, nor graced by any green thing --not even a blade of grass- a tree, nor by the presence of any living creature! Out there in space it whirls its dreary round, with its stupendous mountains cutting the black skies with their jagged peaks above, and casting their inky shadows below; heated by the sun's rays until hotter than the flame of a blast furnace then suddenly immersed into cold that would freeze our air into solid ice, its only companion the terrific rain of meteoric stones driven against it with a force far beyond that of cannon balls, and yet with never a sound as loud as a whisper to break the terrible stillness which envelops it."
