[35] Martin: "Physiography of Wisconsin."
Transcriber's note:
In the scanned version of this book, there is apparently a printer error in the acknowledgments for sources of illustrations (page x) where the author refers to an illustration on page 125. There is no illustration on page 125 in the original text, so the hyperlink in this ebook has been connected to the closest illustration, (caption: This Must Be a Pleasant Day) which is on page 126 in the original text.
Another possible printer error occurred on page 52, where the phrase "branches and holes" appears in the original text. In an effort to relate the context of the phrase, this has been changed to "branches and boles" in this text.
Full-page illustrations have been moved to the nearest paragraph so as not to interrupt the flow of the text. Some page numbers are missing as a result.
Where appropriate, internal hyperlinks within the index link directly to the pertinent chapter heading, section, or illustration referred to on the referenced page. In cases where no appropriate heading was available on the page, the top of the referenced page is linked. In some cases illustrations have been moved from the original location in order to avoid breaks in paragraphs, and to place them more closely to the related paragraph. For example, the index reference for "Hornbills" (page 169) links directly to the illustration now located on page 170.
