It is clear that Captain Burnaby was somewhat puzzled by the qualities displayed by a steed which looked so unpromising; he seeks to explain its performance by the better food it had enjoyed while on the march, and begins to compare the staying power of English horses with those of the Kirghiz pony with doubts as to the superiority of the former. At a later date he records without surprise that his party travelled forty miles in six hours, the horses having gone all the time at a slow steady trot. On his return journey, while staying at Petro-Alexandrovsk, he was given a mount on a little bay, hardly 14 hands high, for a day's hunting; and records that it "danced about beneath me as if he had been carrying a feather-weight jockey for the Cambridgeshire." The Kirghiz and Bokharans who accompanied him evidently thought his weight would prove too much for the pony, and when there was a ditch to be jumped looked round to see how the bay would manage it. "Never a stumble ... the hardy little beast could have carried Daniel Lambert if that worthy but obese gentleman had been resuscitated for the occasion." Finally, Captain Burnaby sums up the performance of this fourteen-hand pony:-- "We had ridden 371 miles in exactly nine days and two hours, thus averaging more than 40 miles a day! At the same time it must be remembered that, with an interval of in all not more than nine days' rest, my horse had previously carried me 500 miles. In London, judging by his size, he would have been put down as a polo pony. In spite of the twenty stone he carried, he had never been either sick or lame during the journey, and had galloped the last 17 miles through the snow to Kasala in one hour and twenty-five minutes." The same author describes a remarkable forced march made in the summer of 1870 by Count Borkh in Russian Tartary. The Count's mission was to test the possibility of taking artillery over the steep and difficult passes in a certain district, and his force consisted of 150 cossacks, and 60 mounted riflemen and a gun. The troops accomplished their journey out and back, 266 miles, in six days; the heat was excessive, the thermometer marking sometimes as much as 117 deg. Fahr. during the day; yet the ponies were none the worse of their exertions, the "sick list" at the end comprising only twelve, all of which suffered from sore backs caused by careless saddling. Other expeditions under similar conditions are mentioned; these go to prove that the endurance of the Tartar pony is affected as little by heat as by cold. POST HORSES IN SIBERIA.
