The opinion
In an action by a landlord against a tenant for years, for waste committed by cutting down trees, evidence of a parol license from the landlord to cut the trees is not admissible. (See 1 R. S. 334, § 1.)
The opinions of witnesses were held not competent upon the question whether cutting the trees was an injury to the inheritance, opinions not being admissible except upon questions of skill and science.
