Upon these briefly related facts it is convenient to deal first of all with the question of T.N.T.'s liability for the proved damages. For this purpose it is necessary to consider what was involved in T.N.T.'s undertaking to carry the goods from the respondent's premises in Melbourne to the various consignees in the other States. This it proceeded to do, as a first step in the carriage, by providing a "pick-up" service in Melbourne. It is not contended that this was not a permissible way of performing part of its obligations under the contract whether the "pick-up" service was conducted by its own servants or by an independent contractor. But however the service was conducted it would be necessary that the first stage of the journey should be from the respondent's premises to T.N.T.'s depot. Obviously the goods would be transported by the "pick-up" service to T.N.T.'s depot in Melbourne in order that they might be sorted and assembled with other goods accepted for carriage upon appropriate trucks for carriage to the other States. It was known to the respondent that T.N.T. maintained a "substantial place" in Footscray Road for this very purpose - a place which is described by the learned trial judge in the following passage: "The depot of T.N.T. is on quite a large area of ground fronting on to the New Footscray Road. It is fairly well secured, being protected either by a wall abutting on the street or by a high fence topped with barbed wire around the curtilage. Generally speaking, sorting and loading at the depot ceased about 5.30 p.m. on Mondays to Thursdays. At the material time, the various consignments were frequently held in the depot overnight but there was a resident caretaker whose duty it was to keep a constant watch on the goods during the hours when the depot was closed. The depot was also furnished with fire extinguishers. There was no sprinkler system. It was constructed of fibro cement sheeting and steel". It was proved that it was Pay's usual practice to take his load at the conclusion of his "pick-up" round to this depot, but, as already appears, there had been about twenty occasions during the preceding twelve months upon which he had been permitted by T.N.T. to depart from this practice. But it is not suggested that the respondent knew of or assented to its goods being taken on any occasion to Pay's home and kept there during the night. Nor is there any suggestion that it was aware that T.N.T.'s depot closed at any particular time and, therefore, that it was not, after that time, available for the receipt of goods which had been picked up. Further there is no evidence that the course adopted on this occasion was justified by some particular custom or usage in the trade. What, therefore, must be presumed to have been the intention of the parties concerning the disposition of the goods at the end of the first stage of their journey? Undoubtedly, notwithstanding the presence in the various contracts of the exempting clauses, T.N.T. impliedly undertook to exercise reasonable care for the safety of the goods at all stages of the various journeys upon which it had undertaken to carry them. This is not of prime importance in the case except in so far as it throws light on the manner in which it was intended that the "pick-up" service should operate. It was, of course, immaterial whether the "pick-up" service - which expression connotes a picking up of the goods by T.N.T. for on-carriage - was conducted by a servant of T.N.T. or by an independent contractor. But it seems clear that if it had been conducted by a servant there can be no warrant for asserting that T.N.T.'s contract with the respondent authorized the former to direct its servant to take any goods which he had picked up to his home and store them there overnight. Such a direction would be clearly inconsistent with the primary obligation which T.N.T. had assumed. The fact that the "pick-up" service was conducted by an independent contractor - although this fact was not known to the respondent - does not in our view affect the matter. It seems to us that it must have been taken to have been implicit in the contract which T.N.T. made with the respondent that its goods would be taken to T.N.T.'s depot and that the depot would be available for their reception at the conclusion of the pick-up round. It is, to our minds, unthinkable that it was within the contemplation of the parties that an extremely valuable consignment of goods was to be kept overnight by T.N.T.'s servant or sub-contractor in the yard of a suburban cottage. On the contrary, the only conclusion consistent with its primary obligation was that they would be taken to and received in the depot at the conclusion of the "pick-up" round. This conclusion is unaffected by consideration of the clause - incorporated in a number of the contracts - that the carrier "is hereby expressly authorized by the Consignor to carry all goods or to have them carried by any method as he in his absolute discretion deems fit and notwithstanding any instruction verbal or otherwise of the Consignor that the goods are to be carried by another method". The italics are ours and it seems to us that the expression "method", which must mean method of carriage, is quite inappropriate to cover the circumstances of this case. What the respondent complains of is not the method which was employed to carry the goods but, rather, that the goods were carried, not to T.N.T.'s depot but to Pay's home and kept there overnight.
