Case No. 1
Without detailing all of the specifications of negligence, the Pickards and Murray seek to hold T. & J. Construction Company liable for damages upon the grounds that it violated G.S. § 14-136, that it violated G.S. § 14-140, that it was negligent in burning the field on a windy day, and that it failed to exercise due care in controlling the fire. They seek to hold Clark Building Company liable for damages upon the grounds that it had notice that T. & J. Construction Company intended to burn the field and that it had the non-delegable duty to comply with G.S. § 14-136 and G.S. § 14-140, and to exercise due care in controlling the fire. They seek to hold Burlington Belt Corporation liable for damages upon the grounds that it had notice that T. & J. Construction Company *603 intended to burn the field and that it had the nondelegable duty to comply with G.S. § 14-136 and G.S. § 14-140, and to exercise due care in controlling the fire. They also seek to hold Burlington Belt Corporation liable upon the grounds of negligence in allowing quantities of flammable waste material to accumulate outside and inside the building which caused the fire to spread rapidly through the building.
G.S. § 14-136 reads, in pertinent part, as follows:
"If any person shall intentionally set fire to any grassland, brushland or woodland, except it be his own property, or in that case without first giving notice to all persons owning or in charge of lands adjoining the land intended to be fired, and without also taking care to watch such fire while burning and to extinguish it before it shall reach any lands near to or adjoining the lands so fired, he shall for every such offense be guilty of a misdemeanor * * *"
G.S. § 14-140 reads, in pertinent part, as follows:
"All persons, firms or corporations who shall * * * set fire to or burn any brush, grass or other material, whereby any property may be endangered or destroyed, shall keep and maintain a careful and competent watchman in charge of such * * * brush or other material while burning. Any person, firm or corporation violating the provisions of this section shall be punishable * * *. Fire escaping from such * * * brush or other material while burning shall be prima facie evidence of neglect of these provisions."
It is clear that the primary purpose of the above quoted statutes is to protect property. Each of them defines the standard of care imposed upon a person who undertakes to burn brush, grass, etc., and a violation of the provisions of either of the statutes constitutes negligence. Benton v. Montague, 253 N.C. 695, 117 S.E.2d 771.
In his charge to the jury the trial judge read the foregoing statutes, but he failed to instruct the jury that a violation of either, or both, of the statutes would constitute negligence; and the plaintiffs assign this as error. In general terms the trial judge explained the difference between the violation of a statute which constitutes negligence per se, and a violation which does not constitute negligence per se. Such an explanation was unnecessary in this case, and without a clear instruction that a violation of either of the statutes in issue would constitute negligence, the jury was left with no guidance as to the application of the statutes to the evidence. G.S. § 1-180. This assignment of error is sustained.
The plaintiffs, the Pickards and Murray, assign as error the granting of motions of nonsuit as to the individual defendants, S. S. Clark, Jr., Wayne Elkins and Curtis Jenkins. The record discloses that these individuals were not doing business as individual proprietorships or partnerships, but as the named corporate defendants. These assignments of error are overruled.
The plaintiffs, the Pickards and Murray, assign as error the striking from their complaint allegations pertaining to G.S. § 14-137 and § 14-139, and the failure of the Court to instruct the jury thereon. Upon this Record on Appeal these statutes have no application, and these assignments of error are overruled.
The plaintiffs, the Pickards and Murray, assign as error the failure of the Court to instruct the jury that Burlington Belt Corporation and Clark Building Company had a non-delegable duty to comply with G.S. § 14-136 and G.S. § 14-140, and to exercise due care in the burning by T. & J. Construction Company. Plaintiffs cite the following principle of law: "The liability of the employer rests upon the ground that mischievous consequences will arise from the work to be done unless precautionary measures are adopted, and the duty to see that those precautionary measures are adopted rests upon the employer, and he *604 cannot escape liability by entrusting this duty to another as an `independent contractor' to perform." Evans v. Rockingham Homes, Inc., 220 N.C. 253, 17 S.E.2d 125. The foregoing principle is applicable to a situation where the "work to be executed, from which, in the natural course of things, injurious consequences must be expected to arise unless means are adopted by which such consequences may be prevented." 27 Am.Jur., Independent Contractors, § 38, p. 515. The employment of T. & J. Construction Company to clear and grade the land preparatory to construction was not work from which in the natural course of things injurious consequences must be expected to arise. We hold that it was proper for the trial judge to submit for jury determination the question of whether under the circumstances of this case the use of fire to clear the land was an inherently hazardous operation, and whether either Burlington Belt Corporation or Clark Building Company, or both, knew or should have known that T. & J. Construction Company intended to use fire for this purpose on the day and under the circumstances prevailing. This assignment of error is overruled.

Case No. 2
Without detailing all of the specifications of negligence, the plaintiffs, Burlington Belt Corporation, et al, seek to hold T. & J. Construction Company liable for damages upon the grounds that it violated G.S. § 14-136, that it was negligent in burning the field on a windy day, and that it failed to exercise due care in controlling the fire. They seek to hold Clark Building Company liable for damages upon the grounds that it had notice that T. & J. Construction Company intended to burn the field and that it had the non-delegable duty to comply with G.S. § 14-136, and to exercise due care in controlling the fire.
Each of the defendants in Case No. 2 allege contributory negligence on the part of Burlington Belt Corporation in allowing an accumulation of flammable waste outside and inside the building.
What has been said in Case No. 1 with respect to the charge of the Court upon the violation of G.S. § 14-136 is equally applicable here. The trial judge failed to instruct the jury that a violation of the statute would constitute negligence, and this failure constituted prejudicial error, and entitles plaintiffs in Case No. 2 to a new trial.
The plaintiffs Burlington Belt Corporation, et al, assign as error the failure of the Court to instruct the jury upon G.S. § 14-137 and G.S. § 14-139. As stated in Case No. 1, upon this Record on Appeal these statutes have no application.
The plaintiffs, Burlington Belt Corporation, et al, make numerous assignments of error to the ruling of the Court in allowing counsel for plaintiffs in Case No. 1 to propound questions to witnesses and in allowing counsel for plaintiffs in Case No. 1 to introduce certain exhibits. These assignments of error are without merit because Burlington Belt Corporation, et al, was successful in its defense of the action in Case No. 1, and the testimony and exhibits could not have been prejudicial.

Case No. 1 and Case No. 2
Since these cases must be retried we refrain from a discussion of the other assignments of error relating to the evidence allowed and rejected; the questions will probably not arise again.
In fairness to the trial judge we note that the Order consolidating these two cases for trial was entered by another Superior Court Judge, and the trial judge may have considered that he was bound to proceed with the consolidated trial. Whether cases should be consolidated for trial is to be determined in the exercise of his sound discretion by the judge who will preside during the trial; a consolidation *605 cannot be imposed upon the judge presiding at the trial by the preliminary Order of another trial judge.
In view of the conflict of interests between the plaintiffs in these two cases, and in view of the confusion as disclosed by the briefs, it appears that the ends of justice will best be served if each case is tried separately. We note that Burlington Belt Corporation, et al, plaintiffs in Case No. 2, joined with one of the defendants in the motion for consolidation; and it appears that Burlington Belt Corporation, et al, were more confused by the consolidation than any other party.
Upon each appeal we hold that the errors in the charge entitle the plaintiffs in each case to a
New trial.
