In Contracts. One to whom goods are bailed; the party to whom personal property is delivered under a con- tract of bailment. His duties are to act in good faith, and perform his undertaking, in respect to the property intrusted to him, with the diligence and care required by the nature of his en gagement. When the bailee alone receives benefit from the bailment, as where he borrows goods or chattels for use, he is bound to exercise extraordinary care and diligence in preserving them from loss or injury; Story, Bailm. § 237; 2 Pars. Contr. 95; 87 N. Ү. 234; 87 Ill. 250; 27 Mo. 549; but he is not an insurer; 9 C. & P. 388; see 44 Barb. 442. When the bailment is mutually beneficial to the parties, as where goods or chattels are hired or pledged to secure a debt, the bailee is bound to exercise ordinary diligence and care in preserving the prop- erty; Edw. Bailm. § 234; 42 Ala. 145; 58 Me. 275; 8 Brewst. 9; 6 Cal. 643. When the bailee receives no benefit from the bailment, as where he accepts goods, chattels, or money to keep without recom- pense, or undertakes gratuitously the per- formance of some commission in regard to them, he is answerable only for the use of the ordinary care which he bestows upon his own property of a similar nature; Edw. Bailm. § 43. See 17 Mass. 479; 14 S. & R. 275; it has been held that such a bailee would be liable only for gross neglect or fraud; 40 Miss. 472; 23 Ark. 61; 57 Pa. 247; 7 Cow. 278; 84 Neb. 426; 154 Pa. 296. The case must have relation to the nature of the property bailed; 2 Stra. 1099;1 Mas. 132; 1 Sneed 248. Where a gratuitous bailee of corporate stock without authority delivers it to the company, which converts the same to its use, he is liable for its value; 87 Mich. 209. These differing degrees of negligence have been doubted. See BAILMENT. The bailee is bound to redeliver or return the property, according to the nature of his engagement, as soon as the purpose for which it was bailed shall have been accom- plished. Nothing will excuse the bailee from delivery to his bailor, except by show- ing that the property was taken from him by law, or by one having a paramount title, or that the bailor's title had terminated; 36 N. Y. 47, 403; 18 Vt. 186; 35 Barb. 191. He cannot dispute his bailor's title; Edw. Bailm. § 73;6 Mackey 255; 29 Mo. App. 233; nor can he convey title as against the bailor, although the purchaser believes him to be the true owner; 46 Mo. App. 313. The bailee has a special property in the goods or chattels intrusted to him, sufficient to enable him to defend them by suit against all persons but the rightful owner. The depositary and mandatary acting gratui- tously, and the finder of lost property, have this right; Edw. Bailm. § 245; 13 Johns. 147. A bailee with a mere naked authority, having a right to remuneration for his trouble, but coupled with no other interest, may support trespass for any injury amounting to a trespass done while he was in the actual possession of the thing; Edw. Bailm. 37; 13 Wend. 63; 35 Me. 55; 46 Ν. Υ. 291. A bailee may recover in trover for goods wrongfully converted by a third person; 47 Ill. App. 87. A bailee for work, labor, and services, such as a mechanic or artisan who receives chattels or materials to be repaired or manu- factured, has a lien upon the property for his services; 2 Pars. Contr. 145, 146; 3 id. 270-273; 6 Denio 628; 10 Wend. 318; 15 Mass. 242. Other bailees, innkeepers, common carriers, and warehousemen, also, have a lien for their charges.
