With regard to the animals, I should recommend an equal number of horses as of bullocks; since it has been found that the latter, though slow, travel better over swampy ground than horses, which, on the other hand, are preferable for expeditious journeys, to which bullocks would never be equal. One of the colonial pack-saddles weighs fifty pounds complete, and is preferable to those sent out from England. This, with a load of 250 lbs. is sufficient for any animal, since it enables the men to place a part of their provisions with the general loads. The difficulty of keeping the backs of the animals free from injury, more especially where any blemish has before existed, is exceedingly great. They should undergo an examination twice a-day, that is, in the morning prior to moving off, and in the afternoon before they are turned out to feed; and measures should then be taken to ease them as circumstances require. I never suffered the saddles to be removed from the backs of the animals under my charge for twenty minutes after the termination of the journey for the day, in order to guard against the effects of the sun; and where the least swelling appeared the saddle was altered and the place dressed. Yet, notwithstanding all this care and attention, several both of the horses and bullocks were at one time in a sad condition, during the first journey,--so much so as almost to paralyse our efforts. It would be advisable that such animals as are entirely free from blemish should be chosen for the service of expeditions, for, with proper management they might he kept in order. The anxiety of mind attendant on a bad state of the animals is really quite embarrassing, for it not only causes a delay in the movements, but a derangement in the loads. Other animals are overburdened, and there is no knowing where the evil will stop. In addition to the pack-animals, I would recommend the employment of a dray or cart under any practicable circumstances. It serves to carry necessary comforts, gives an expedition greater facility for securing its collections, and is of inconceivable advantage in many other respects. ISSUE OF PROVISIONS.
