Acting under the Cedar Rust Act of Virginia, Acts Va. 1914, c. 36, as amended by Acts Va. 1920, c. 260, now embodied in Va. Code (1924) as sections 885 to 893, defendant in error, the state entomologist, ordered the plaintiffs in error to cut down a large number of ornamental red cedar trees growing on their property, as a means of preventing the communication of a rust or plant disease with which they were infected to the apple orchards in the vicinity. The plaintiffs in error appealed from the order to the circuit court of Shenandoah county which, after a hearing and a consideration of evidence, affirmed the order and allowed to plaintiffs in error $100 to cover the expense of removal of the cedars. Neither the judgment of the court nor the statute as interpreted allows compensation for the value of the standing cedars or the decrease in the market value of the realty caused by their destruction whether considered as ornamental trees or otherwise. But they save to plaintiffs in error the privilege of using the trees when felled. On appeal the Supreme Court of Appeals of Virginia affirmed the judgment. Miller v. State Entomologist, 146 Va. 175, 135 S. E. 813. Both in the circuit court and the Supreme Court of Appeals plaintiffs in error challenged the constitutionality of the statute under the due process clause of the Fourteenth Amendment and the case is properly here on writ of error. Judicial Code, § 237a (28 USCA § 344).
The Virginia statute presents a comprehensive scheme for the condemnation and destruction of red cedar trees infected by cedar rust. By section 1 it is declared to be unlawful for any person to 'own, plant or keep alive and standing' on his premises any red cedar tree which is or may be the source or 'host plant' of the communicable plant disease known as cedar rust, and any such tree growing within a certain radius of any apple orchard is declared to be a public nuisance, subject to destruction. Section 2 makes it the duty of the state entomologist, 'upon the request in writing of ten or more reputable freeholders of any county or magisterial district, to make a preliminary investigation of the locality * * * to ascertain if any cedar tree or trees * * * are the source of, harbor or constitute the host plant for the said disease * * * and constitute a menace to the health of any apple orchard in said locality, and that said cedar tree or trees exist within a radius of two miles of any apple orchard in said locality.' If affirmative findings are so made, he is required to direct the owner in writing to destroy the trees and, in his notice, to furnish a statement of the 'fact found to exist whereby it is deemed necessary or proper to destroy' the trees and to call attention to the law under which it is proposed to destroy them. Section 5 authorizes the state entomologist to destroy the trees if the owner, after being notified, fails to do so. Section 7 furnishes a mode of appealing from the order of the entomologist to the circuit court of the county, which is authorized to 'hear the objections' and 'pass upon all questions involved,' the procedure followed in the present case.
As shown by the evidence and as recognized in other cases involving the validity of this statute, Bowman v. Virginia State Entomologist, 128 Va. 351, 105 S. E. 141, 12 A. L. R. 1121; Kelleher v. Schoene (D. C.) 14 F. (2d) 341, cedar rust is an infectious plant disease in the form of a fungoid organism which is destructive of the fruit and foliage of the apple, but without effect on the value of the cedar. Its life cycle has two phases which are passed alternately as a growth on red cedar and on apple trees. It is communicated by spores from one to the other over a radius of at least two miles. It appears not to be communicable between trees of the same species, but only from one species to the other, and other plants seem not to be appreciably affected by it. The only practicable method of controlling the disease and protecting apple trees from its ravages is the destruction of all red cedar trees, subject to the infection, located within two miles of apple orchards.
The red cedar, aside from its ornamental use, has occasional use and value as lumber. It is indigenous to Virginia, is not cultivated or dealt in commercially on any substantial scale, and its value throughout the state is shown to be small as compared with that of the apple orchards of the state. Apple growing is one of the principal agricultural pursuits in Virginia. The apple is used there and exported in large quantities. Many millions of dollars are invested in the orchards, which furnish employment for a large portion of the population, and have induced the development of attendant railroad and cold storage facilities.
