to set the Foxhall colt into a gallop, and forthwith depart in search of the Naulahka. He mechanically drove his heels home, and shortened his rein under the impulse of the thought; but the colt's leap beneath him recalled him to his senses, and he restrained himself and his mount with the same motion.
His familiarity with the people's grotesque nomenclature left him unimpressed by the Cow's Mouth as a name for a spot, but he gave some wonder to the question why the thing should be in the Cow's Mouth. This was a matter to be laid before Estes.
'These heathen,' he said to himself, 'are just the sort to hide it away in a salt-lick, or bury it in a hole in the ground. Yes; a hole is about their size. They put the State diamonds in cracker-boxes tied up with boot-laces. The Naulahka is probably hanging on a tree.'
As he trotted toward the missionary's house, he looked at the hopeless landscape with new interest, for any spur of the low hills, or any roof in the jumbled city, might contain his treasure.
Estes, who had outlived many curiosities, and knew Rajputana as a prisoner knows the bricks of his cell, turned on Tarvin, in reply to the latter's direct question, a flood of information. There were mouths of all kinds in India, from the Burning Mouth in the north, where a jet of natural gas was worshipped by millions as the incarnation of a divinity, to the Devil's Mouth among some forgotten Buddhist ruins in the furthest southern corner of Madras.
There was also a Cow's Mouth some hundreds of miles away, in the courtyard of a temple at Benares, much frequented by devotees; but as far as Rajputana was concerned, there was only one Cow's Mouth, and that was to be found in a dead city.
The missionary launched into a history of wars and rapine, extending over hundreds of years, all centring round one rock-walled city in the wilderness, which had been the pride and the glory of the kings of Mewar. Tarvin listened with patience as infinite as his weariness--ancient history had no charm for the man who was making his own town--while Estes enlarged upon the past, and told stories of voluntary immolation on the pyre in subterranean palaces by thousands of Rajput women who, when the city fell before a Mohammedan, and their kin had died in the last charge of defence, cheated the conquerors of all but the empty glory of conquest. Estes had a taste for archæology, and it was a pleasure to him to speak of it to a fellow-countryman.
By retracing the ninety-six miles to Rawut Junction, Tarvin might make connection with a train that would carry him sixty-seven miles westward to yet another junction, where he would change and go south by rail for a hundred and seven miles; and this would bring him within four miles of this city, its marvellous nine-storeyed tower of glory, which he was to note carefully, its stupendous walls and desolate palaces. The journey would occupy at least two days. At this point Tarvin suggested a map, and a glance at it showed him that Estes proposed an elaborate circus round three sides of a square, whereas a spider-like line ran more or less directly from Rhatore to Gunnaur.
'This seems shorter,' he said.
'It's only a country road, and you have had some experience of roads in this State. Fifty-seven miles on a kutcha road in this sun would be fatal.'
Tarvin smiled to himself. He had no particular dread of the sun, which, year by year, had stolen from his companion something of his vitality.
'I think I'll ride, anyhow. It seems a waste to travel half round India to get at a thing across the road, though it is the custom of the country.'
He asked the missionary what the Cow's Mouth was like, and Estes explained archæologically, architecturally, and philologically to such good purpose that Tarvin understood that it was some sort of a hole in the ground--an ancient, a remarkably ancient, hole of peculiar sanctity, but nothing more than a hole.
Tarvin decided to start without an hour's delay. The dam might wait until he returned. It was hardly likely that the King's outburst of generosity would lead him to throw open his jails on the morrow. Tarvin debated for a while whether he should tell him of the excursion he was proposing to himself, and then decided that he would look at the necklace first, and open negotiations later. This seemed to suit the customs of the country. He returned to the rest-house with Estes' map in his pocket to take stock of his stable. Like other men of the West, he reckoned a horse a necessity before all necessities, and had purchased one mechanically immediately after his arrival. It had been a comfort to him to note all the tricks of all the men he had ever traded horses with faithfully reproduced in the lean, swarthy Cabuli trader, who had led his kicking, plunging horse up to the verandah one idle evening; and it had been a greater comfort to battle with them as he had battled in the old days. The result of the skirmish, fought out in broken English and expressive American, was an unhandsome, doubtful-tempered, mouse-coloured Kathiawar stallion, who had been dismissed for vice from the service of his Majesty, and who weakly believed that, having eaten pieces of the troopers of the Deolee Irregular Horse, ease and idleness awaited him. Tarvin had undeceived him leisurely, in such moments as he most felt the need of doing something, and the Kathiawar, though never grateful, was at least civil. He had been christened Fibby Winks in recognition of ungentlemanly conduct and a resemblance which Tarvin fancied he detected between the beast's lean face and that of the man who had jumped his claim.
Tarvin threw back the loin cloth as he came upon Fibby drowsing in the afternoon sun behind the rest-house.
'We're going for a little walk down town, Fibby,' he said.
The Kathiawar squealed and snapped.
'Yes; you always were a loafer, Fibby.'
Fibby was saddled by his nervous native attendant, while Tarvin took a blanket from his room and rolled up into it an imaginative assortment of provisions. Fibby was to find his rations where Heaven pleased. Then he set out as lightheartedly as though he were going for a canter round the city. It was now about three in the afternoon. All Fibby's boundless reserves of illtemper and stubborn obstinacy Tarvin resolved should be devoted, by the aid of his spurs, to covering the fifty-seven miles to Gunnaur in the next ten hours, if the road were fair. If not, he should be allowed another two hours. The return journey would not require spurs. There was a moon that night, and Tarvin knew enough of native roads in Gokral Seetarun, and rough trails elsewhere, to be certain that he would not be confused by cross-tracks.
It being borne into Fibby's mind that he was required to advance, not in three directions at once, but in one, he clicked his bit comfortably in his mouth, dropped his head, and began to trot steadily. Then Tarvin pulled him up, and addressed him tenderly.
'Fib, my boy, we're not out for exercise--you'll learn that before sundown. Some galoot has been training you to waste your time over the English trot. I'll be discussing other points with you in the course of the campaign; but we'll settle this now. We don't begin with crime. Drop it, Fibby, and behave like a man-horse.'
Tarvin was obliged to make further remarks on the same subject before Fibby returned to the easy native lope, which is also a common Western pace, tiring neither man nor beast. By this he began to understand that a long journey was demanded of him, and, lowering his tail, buckled down to it.
At first he moved in a cloud of sandy dust with the cotton wains and the country carts that were creaking out to the far distant railway at Gunnaur. As the sun began to sink, his gaunt shadow danced like a goblin across low-lying volcanic rock tufted with shrubs, and here and there an aloe.
The carters unyoked their cattle on the roadside, and prepared to eat their evening meal by the light of dull red fires. Fibby cocked one ear wistfully toward the flames, but held on through the gathering shadows, and Tarvin smelt the acrid juice of bruised camel-thorn beneath his horse's hoofs. The moon rose in splendour behind him, and, following his lurching shadow, he overtook a naked man who bore over his shoulder a stick loaded with jingling bells,
