ROUND OR SPLIT POSTS.
MINIMUM OF SAP ESSENTIAL
Is a split post as durable as a round fence post? This question is frequently asked. One kind of post will last about as long as the other if the amount of heartwood is the same in both, laboratory experts declare. But if the percentage of sap-, wood is increased by splitting, the split post will be less durable, and if the percentage of hardwood is increased, it will toe more durable than a round one. Posts of spruce, hemlock, or any of the truce firs are exJ ceptions to this rule, because their heartwood and sapwood are about equally durable. When posts are to be treated with creosote or other preservative a round post is preferable to a split post, because of the comparative ease with which the sapwood can toe treated. The heart faces on split posts do not, as a rule, absorb preservative well. Split red oak posts will take trea f ment, because the wood is very porous, but the heart faces of split posts of many other species, notably white oak, red gum and Douglas fir, resist the penetration of preservative, even under heavy pressure.
