The antique log cabin shown in this photo was found along the Susquehanna River in Pennsylvania during a log cabin driving tour we took in 2007.
In photos and with comments below we point out some of the construction techniques and the resulting condition of these homes. These small cabins varied considerably in condition; the second cabin in this row was collapsing, almost certainly because its owner did not maintain the roof, which was collapsing when we found these homes.
The principal causes of extensive rot damage we observed on this string of log cabins along the river included:
Failure to keep the roof intact, letting water enter the structure and run down both sides of the log walls
Logs at ground level not protected from soil contact
Leaks around the chimneys, sending water down the logs behind and abutting the chimney
Rot at the ends or at lap joints of logs in an antique log homes is a principal point of damage on these structures, as evident in this photo (left) of an antique log structure in Molde, Norway.
Notice that it was the lower splice log that has suffered most in this construction detail.
Notice the careful detailing at the log ends in this photo of another antique log structure in Norway?
Those sloping covers and sloping sides of wood piers shed water to extend the life of these wood members.
Below we show what happens when the ends of logs are not properly protected from water uptake.
Here we show that a simple stone slab can break the insect and water path between the supporting structure of a log home and its wooden pier.
This construction detail was observed in many log homes in Norway.

Breyer, Kenneth Fridley, Kelly Cobeen, David Pollock, McGraw Hill, 2003, ISBN-10: 0071379320, ISBN-13: 978-0071379328 This book is an update of a long-established text dating from at least 1988 (DJF); Quoting: This book is gives a good grasp of seismic design for wood structures. Many of the examples especially near the end are good practice for the California PE Special Seismic Exam design questions. It gives a good grasp of how seismic forces move through a building and how to calculate those forces at various locations.THE CLASSIC TEXT ON WOOD DESIGN UPDATED TO INCLUDE THE LATEST CODES AND DATA. Reflects the most recent provisions of the 2003 International Building Code and 2001 National Design Specification for Wood Construction.

Straw Bale Home Design, U.S. Department of Energy provides information on strawbale home construction - original source at http://www.energysavers.gov/your_home/designing_remodeling/index.cfm/mytopic=10350
More Straw Bale Building: A Complete Guide to Designing and Building with Straw (Mother Earth News Wiser Living Series), Chris Magwood, Peter Mack, New Society Publishers (February 1, 2005), ISBN-10: 0865715181 ISBN-13: 978-0865715189 - Quoting: Straw bale houses are easy to build, affordable, super energy efficient, environmentally friendly, attractive, and can be designed to match the builder’s personal space needs, esthetics and budget. Despite mushrooming interest in the technique, however, most straw bale books focus on “selling” the dream of straw bale building, but don’t adequately address the most critical issues faced by bale house builders. Moreover, since many developments in this field are recent, few books are completely up to date with the latest techniques. More Straw Bale Building is designed to fill this gap. A completely rewritten edition of the 20,000-copy best--selling original, it leads the potential builder through the entire process of building a bale structure, tackling all the practical issues: finding and choosing bales; developing sound building plans; roofing; electrical, plumbing, and heating systems; building code compliance; and special concerns for builders in northern climates.
