Waffles would have been an invaluable customer to Thornton if the former's groom, Mr. Figg, had not been rather too hard with his 'reg'lars.' He insisted on Caingey dividing whatever he got out of his master with him. This reduced profits considerably; but still, as it was a profession that did not require any capital to set up with, Thornton could afford to be liberal, having only to tack on to one end to cut off at the other. After the opening Sponge gave as they rode home with the hounds, Thornton had no difficulty in sounding him on the subject. 'You'll not think me impertinent, I hope,' observed Caingey, in his most deferential style, to our hero when they met at the News'-room the next day--'you'll not think me impertinent, I hope; but I think you said as we rode home, yesterday, that you didn't altogether like the brown horse you were on?' '_Did I?_' replied Mr. Sponge, with apparent surprise; 'I think you must have misunderstood me.' 'Why, no; it wasn't exactly that,' rejoined Mr. Thornton, 'but you said you liked him better than you did, I think?' 'Ah! I believe I did say something of the sort,' replied Sponge casually--'I believe I did say something of the sort; but he carried me so well that I thought better of him. The fact was,' continued Mr. Sponge, confidentially, 'I thought him rather too light mouthed; I like a horse that bears more on the hand.' 'Indeed!' observed Mr. Thornton; 'most people think a light mouth a recommendation.' 'I know they do,' replied Mr. Sponge, 'I know they do; but I like a horse that requires a little riding. Now this is too much of a made horse--too much of what I call an old man's horse, for me. Bullfrog, whom I bought him of, is very fat--eats a great deal of venison and turtle--all sorts of good things, in fact--and can't stand much tewing in the saddle; now, I rather like to feel that I am on a horse, and not in an arm-chair.' 'He's a fine horse,' observed Mr. Thornton. 'So he ought,' replied Mr. Sponge; 'I gave a hatful of money for him--two hundred and fifty golden sovereigns, and not a guinea back. Bullfrog's the biggest screw I ever dealt with.' That latter observation was highly encouraging to Thornton. It showed that Mr. Sponge was not one of your tight-laced dons, who take offence at the mere mention of 'drawbacks,' but, on the contrary, favoured the supposition that he would do the 'genteel,' should he happen to be a seller. 'Well, if you should feel disposed to part with him, perhaps you will have the kindness to let me know,' observed Mr. Thornton; adding, 'he's not for myself, of course, but I think I know a man he would suit, and who would be inclined to give a good price for him.' 'I will,' replied Mr. Sponge; 'I will,' repeated he, adding, 'if I _were_ to sell him, I wouldn't take a farthing under three 'underd for him--three 'underd _guineas_, mind, _not punds_.' 'That's a vast sum of money,' observed Mr. Thornton.
