When any suits shall be entered by the attorney general under the act to which this is a further supplement, it shall be by scire facias sur liens, which shall be directed for service to the sheriff of the county in which the land is situate; and if he finds it necessary to insure a service of said writ, he may call to his aid the county surveyor, who shall act as his deputy, for the purpose of serving such writ; and all such writs shall be made returnable to the court of common pleas of the county wherein such lands are situate, where all such suits shall be tried.
