The Bible for School and Home is the revised name for the series by J. Paterson Smyth referenced by Charlotte Mason under the original name The Bible for the Young. The completed series contained seven volumes, four covering the Hebrew scriptures and three covering the Gospels. Although this series is in the public domain, not all the books are apparently available online, exactly, but I have been able to find sources for all of them (I think).
Schellermark Ministries has a site called The Writings of J. Paterson Smyth, from which you can order CD's of various volumes for $5 each. I believe these CD's contain scans of the pages, but I haven't yet received one so I can't say for sure. Joshua and the Judges is available here as a typed-out pdf which can be downloaded.
Hathi Trust Digital Library links to scans of the first three volumes; see the links labeled Full View at the bottom of the page.
Prophets and Kings, volume 4 in the series, can be accessed as an html file.
UPDATE 4/17/2012: Schellermark Ministries' new site now has pdf's of all the volumes of the Bible for School and Home available as pdf's to download.
