“Before he can be held liable to plaintiffs for any damage caused through the negligence of Thomas Young in operating the automobile in question, the plaintiff must prove,, by a preponderance of the evidence, — that is, by the greater weight or value of the evidence, — that, at the time the plaintiffs were injured, Thomas Young was the agent, servant, or employee of E.
