Excerpt from A Guide to Profitable Tree UtilizationSuch a conclusion would be erroneous. The total conversion sur plus of this tree is the sum of the conversion surpluses of its logs minus the direct cost of marking and felling (60 cents), or no cents. The fact that this conversion surplus is positive indicates that the tree is worth felling. If the top log is culled, the total conver sion surplus of the tree is reduced to 20 cents, which is another way of saying that the top log is worth taking.Here, incidentally, it is seen that the method of conversion sur plus may be used to segregate those trees that will not pay their own 'way. If the sum of the conversion surpluses of'the logs in a tree does not equal or exceed the joint costs of harvesting, the tree is a cull.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
