Excerpt from Estimating the Weight of Douglas-Fir Tree Boles and Logs With an Iterative Computer Model About one-half of the population trees (93) were felled and bucked into various log lengths. Each log length was measured, and the log was tagged for identification. The logs were then yarded (using horses) to a landing and weighed with a self loading log truck and platform scales. A total of 326 logs were weighed. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
