The Rover Boys on the Farm; or, Last Days at Putnam Hall

My Dear Boys: With this I present to you The Rover Boys on the Farm, the twelfth volume in the Rover Boys Series for Young Americans.
It is a large number of volumes to write about one set of characters, isn't it? When I started the series, many years ago, I had in mind, as I have told you before, to pen three books, possibly four. But as soon as I had written The Rover Boys at School, The Rover Boys on the Ocean, and The Rover Boys in the Jungle, there was a cry for more, and so I wrote The Rover Boys Out West, On the Great Lakes, In the Mountains, On Land and Sea, In Camp, On the River, On the Plains, and then In Southern Waters, where we last left our heroes.
In the present story, as promised in the last volume, the scene is shifted back to the farm and to dear old Putnam Hall, with their many pleasant associations. As before, Sam, Tom and Dick are to the front, along with several of their friends, and there are a number of adventures, some comical and some strange and mystifying. At the school the rivalries are as keen as ever, but the Rover boys are on their mettle, and prove their worth on more than one occasion.
Again I thank my numerous readers for all the kind words they have spoken about my stories. I hope the present volume will please them in every way.
Affectionately and sincerely yours,
Edward Stratemeyer
Sam, this isn't the path.
I know it, Tom.
We've missed our way, went on Tom Rover, with a serious look on his usually sunny face.
It looks that way to me, answered Sam Rover, his younger brother. I think we made a wrong turn after we slid down the cliff.
