The letter tells the story!
If our Winter Annuals had been loaded at one time Captain Billy would
have filled an entire mail train. Hereafter, Gentle Reader, your news
dealer will have the Whiz Bang on the 15th of the month, and because of
our enormous orders, we will, in future, mail a few truck loads every
day throughout the full month, all magazines to be held at the various
postoffices until the 15th for delivery. In conclusion, I thank you for
your indulgence at delays in getting your Whiz Bang and your Winter
Annual. The old Whiz Bang Farm has been a busy spot these past few
months. Yours for fun,
