the book is one of the better greek readers written by WHDR, a great Christ's man. it shows evidence of the author's obsession with the direct method, that is teaching a language with solely the use of that tongue. (indeed it was WHDR who created the use of the direct method with latin and greek, though not with great reception from other schoolmasters). it was pusblished in 1909 so, unsurprisingly, is not blessed with an isbn. it is not easy to find, but best of luck.
