The enhancement of efficiency and well-being, and, perhaps more than all, of the personal self-respect of the individual driver, which has been the result both of the new organised discipline and of the new _esprit de corps_, is very marked. It remains only to prove conclusively that in the field, the inter-organisation of transport can be sufficiently maintained to serve its object, without interfering with other military considerations. The allotting of their transport to combatant units, according to their exact requirements, without destroying the organisation of the transport units themselves, often constitutes a problem which a chief transport officer has difficulty in solving. The _via media_, which on this Expedition has afforded a solution, has been to let the transport organisation, if necessary, go to the winds on the march itself, but to give it the first claim to consideration when once a column has reached camp. Those irregular corps which supplemented the permanent military pack transport were most indispensable but delightfully heterogeneous. It may be interesting to describe the journey of, say, a maund of rice from Siliguri to Lhassa on these various forms of transport. Wrapped in its waterproof to keep off the rain torrents, the rice was dumped into a bullock-cart at Siliguri. If the road did not collapse from a landslip at any awkward moment and so drop the bullock-cart and its contents _en masse_ into the Teesta river--a not infrequent occurrence--the rice-bag probably reached Rangpo. From there it probably proceeded for a few marches on the back of a pack bullock, a patient beast who moved slowly, and whose feet in that damp climate got very tender, and on those stony paths very sore. Later on it reached steep gradients where the pack bullock could no longer carry it, and it was handed over for several marches to a cooli. The cooli would be a native of some hill district of India (Panch, for instance, or Darjiling). He and the comrades to whom he passed it on would take it over either the Jalap-Là or the Natu-Là, down into the Chumbi valley. From here a pack mule or an 'irregular' pack pony would take it up to Phári. From here across the Phári plain through Tuna and Kalatso and as far as Menza it would lie in an ekka, for this was flat country, and it had seemed worth while and eventually proved a signal success to drag up from India several hundred of those plainly built but strong little two-wheeled carts called ekkas, which hold five maunds each, and can be used on almost any road, however rough, provided it is wide enough to hold both wheels. These ekkas had been run up behind their ponies as far as possible, then taken to pieces, and carried in fragments on the backs of coolis over the passes and up on to the Phári plain, where, at a height of 15,000 feet, they were put together again and plied to and fro, at first greatly to the astonishment of the resident Tibetan, who had never seen any wheels
