Even the sutler's horse, intoed, sway-backed and wheezy, who had habitually worn a ragged calfskin over his rump as he stood on frosty nights before the war, tied to a rail fence while his owner talked politics in the village grocery, claimed superiority. The picturesque talisman U. S. upon his shoulder was the only badge of honor permitted to the Army Mule, save when the whip-lash had cut out a slice of his skin as a souvenir. But even this significant lettering was often so inexpertly executed as to serve no decorative purpose whatever. It was infinitely less effective than a bran mash to poultice his internal pains, or a roached mane to command external admiration. With one foot over the trace and both eyes blinking, the last state of that Mule was worse than the first. To him all alleged or attempted adornments were superfluous and unsatisfying.
Here then was the sine of an arc which did not recognize equality in the cosine of its supplement. The sorriest horse, though just released from the duty of transporting miscellaneous triturations of real estate in a dumpcart, with his alimentary system painfully void of toothsome internal decoration, outranked the smoothest, softest Mule, whether young or aged, black or sorrel, dun or gray. Nevertheless the explanation of the fact that a rat-tailed cat-hammed Mule weighing five hundred and thirty pounds, saw-backed, sharktoothed, and knobby with protruding bones from throat-latch to crupper, could draw heavier loads than a round robust Norman-Percheron horse weighing a ton, remains to this day unknown, unguessable. Invidious comparison is gross violation of consanguinity equal to marrying one's widow's sister. The checked, banged and bitted high steppers of Fairmount park, dear to the heart of placid quakers because their nerves can endure the strain of "Curfew Shall Not Toll Tonight," or equivalent atrocities, will not be involved therein; their pinked tennis-tan harness, silver trimmed, with monograms at the joints and red stitches in the tug, constitute a perpetual, effectual bar. There was one glory of horse and another glory of mule, but no mule differed from another mule in glory, by any palpable percentage. They had little regard for the affinity of a somewhat common maternity. But whether rearing, plunging, kicking, rolling in the mire or pawing at the clouds, they were all equal. They met upon the level and parted on the square.
