Abstract of the Decision.

l.i Jury, § 80 —when question asTced juror on voir dire is proper ground for peremptory challenge. Where a juror was asked on voir dire if he would give plaintiff all the damages he was entitled to under the law and the evidence in case the jury found the defendant guilty and that plaintiff was entitled to damages, held that the question was competent and allowable as ground for a peremptory challenge.

2. Jury, § 53 —when answer of juror on voir dire shows his competency.- An answer of a witness to a question, if he would give plaintiff all the damages he was entitled to under the law and the evidence in the case, in case the jury found the defendant guilty and that plaintiff was entitled to damages, that he would go according to his own judgment on the evidence and the law, shows his competency. .

3. Mines and minerals, § 176 —when evidence sufficient to show unlawful accumulation of refuse. The preponderance of the evidence held' to show that refuse was allowed to accumulate on both sides of the haulage road in defendant’s coal mine in violation of the statute (J. & A. j[ 7489), and as charged in the declaration, in an action by a mine employee to recover damages for personal injuries charged to have been sustained by reason of such refuse.

4. Evidence, § 365 —when opinions of experts are not competent. The opinions of expert witnesses are not competent evidence as to actual conditions, and their safety, which are matters of common observation.

5. Instructions, § 87 -—when instruction on preponderance of evidence is proper. An instruction as to the sufficiency of a slight preponderance of evidence is proper.

7. Mines and minerals, § 191 —when instruction on liability of mine owner is not erroneous. " In an action against a mine owner by an employee for damages for personal injuries, an instruction* setting out the particular provisions of the statute charged in the declaration to have been violated, and stating that if the defendant failed to comply with such provisions and such violation caused plaintiff’s injury the jury should find defendant guilty, not approved but held not erroneous.

8. Instructions, § 20 —when requested cautionary instruction properly refused.

11. Mines and minerals, § 194 —when refusal of instruction as to nonliability of owner if mine examiner did not consider mine unsafe proper. An instruction that if the mine examiner did not consider a certain condition in the mine dangerous the plaintiff could not recover, held erroneous and properly refused, in an action by a mine employee to recover damages for personal injuries sustained in defendant’s mine.

12. Instructions, § 20 —refusal of cautionary as not error. Cautionary instructions held permissible, but refusal to give same not error.
