This week we're offering another instructive rhyme from Nautical Nursery Rhymes by Billy Ringbolt, which resides in the Peterson, Peter H. (Capt.) Papers, (SAFR 18665, HDC 571):
A sailing ship when under sail,
Or being towed must never fail
Her side lights to let others see,
As told by Regulation Three;,
And also, as we all should know,
A masthead light must never show.
