Of the payment for conveyance by sea, £150,000 is, on such estimate as can be made, assignable to the conveyance of letter mails. The cost of the conveyance of letter mails is therefore-- £ By Railway 1,238,529 " Road 331,005 " Sea 150,000 ---------- Total £1,719,534 ========== And the cost of the conveyance of parcel mails is-- £ By Railway 1,197,037 " Road 331,005 " Sea 27,260 ---------- Total £1,555,302 ========== TABLE N CONVEYANCE: ANALYSIS OF COST. LETTER MAILS. _Total Cost_, £1,719,534. Cost of conveyance is assigned between the various classes of packets in proportion to the gross weight. +----------------------------------------------------------------+ | Description of Packet. | Gross Weight. | Cost of | | | [633] | Conveyance. | +--------------------------+------------------+------------------+ |Ordinary Letter Packets-- | lb. | £ | | (a) Not exceeding 1 oz. | 67,200,000 | 437,734 | | (b) Over 1 oz., not | | | | exceeding 4 oz. | 41,700,000 | 271,600 | | (c) Over 4 oz. | 54,000,000 | 351,700 | |Postcards | 8,203,000 | 53,450 | |Halfpenny Packets | 37,705,000 | 245,600 | |Newspaper Packets | 55,192,000 | 359,450 | +--------------------------+------------------+------------------+ * * * * * TABLE O BUILDINGS. _Total Cost_, £706,614. Twelve times as much office accommodation is required in respect of a parcel as in respect of a packet other than a parcel (Table D). Hence-- The total cost of buildings may be divided as between parcels on the one hand and all packets other than parcels on the other hand in the ratio-- 133,663,000 × 12 : 5,831,550,000 i.e. 1 : 3.6357 The total cost for buildings chargeable to parcels is therefore £152,428, and the total cost for buildings chargeable to other packets is £554,186. The latter sum is assigned between the respective classes of packets in proportion to the gross weight of each class (Table N) as follows:-- Cost for Buildings.
