IN THE MAIL: Sam Martin’s The Curious Boy’s Book of Adventure: 100 Hijinks and Escapades. Lots of advice on things like building radios, how to juggle, lighting a fire without matches, etc.

Some people will see this as a me-too response to The Dangerous Book for Boys, and I suppose there’s probably something to that. But it’s also evidence that the Dangerous Book has opened up a previously dormant genre and gotten it a lot more attention.
