Transcriber’s Note
A hyperlinked table of contents was added before chapter 1.
In the following compound words, the hyphen was removed to conform to majority use in text:
| exhaust-blast | exhaust blast |
| jet-motors | jet motors |
| jet-planes | jet planes |
| pilot-gyros | pilot gyros |
| space-travel | space travel |
| wing-flaps | wing flaps |
The following compounds, with and without a hyphen, were left as found because of equal prevalence of both forms:
| blood-stained | bloodstained |
| wood-blocks | wood blocks |
One compound was split since joined it suggested an inapposite meaning:
| cherrystone | cherry stone |
A host of compounds were left both hyphenated and separate depending on their part of speech, for example:
| science-fiction | science fiction |
| (adjective) | (noun) |
One typo was corrected:
| spendid | splendid |
