I assume “line the boy with concrete” to mean “line the ditch with concrete”.

There are a bunch of irrigation ditches in places like Arizona that are concrete lined simply to assure the water makes it to the field rather than soaking into the very dry ground under the ditch.

So my take would be size and “same size that a boy turns into a man” is probably a good way to describe the choice, i.e. judgement call by mapper.

Cheers!
