"Castle Island [Boston Harbor] where the ships go by" is the title and it's from The Port of the Puritans, by Winfield M. Thompson, published in the August 1911 edition of Harper's Monthly Magazine.

Thompson was a travel writer with a vast knowledge of Maine and New England, to judge from the Google entries in his name. I have no bio information on him and we don't much about Bill Aylward, who was one of the great painters and illustrators of his time. There should be no argument there. I'm using examples of his work to set the tone for August vacations. I hope you have an enjoyable one. Meanwhile, here's a link to some previous material I've posted here about Aylward and his excellent work.
