A google search reveals a number of publications, few of which are posted in entirety.

This info is from the system as used in Mambwe. The circular mounds are a meter high, with 10 cm of soil on top.

Thanks. The principal is similar. Here's from a quote from an older book describing it:

Constructed similarly to a compost pile, the mound garden beds support growing vegetables during the decomposition process. The plants benefit from the warmth of decomposition, as in a hotbed, and the bed provides a rich garden soil. Since the mound is builit of such coarse organic matter as fruit tree prinings and the like, and also because it is not disturbed, the decomposition process produces a much milder heat than a hot bed, and is reported to continue for five or six years.

Each mound is a long berm about 5 feet wide at its base and 3 or 4 feet tall at the time of its construction, though it sinks as the plant materials decompose. A shallow trench is dug out for the area of the new mound, and the sods are removed in squares and saved. A 24-inch-wide and 15-inch-high core of small branches cut in short pieces is laid down the middle of this trench, and the sod that was removed is placed grass side down on top of the branches. Atop the sod goes 12 inches of leaves weighted down with a few spadefuls of soil. etc.

Sounds similar to the "hugelkultur" that Frank Teuton described here some years back.
