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. The war-horse of the late unpleasantness has been chiseled and painted in many attitudes--especially that of unsupported suspension in the atmosphere, with extended nose and carefully adjusted legs. Sheridan's horse, propelled down the wild, disheveled turnpike by "a terrible oath" at the rate of five (5) miles per stanza, hangs to the canvas in a posture unnatural as that of some artillery steed swung by the breeching from a tree after a caisson explosion. The war-horse has been sufficiently pictured and carved. But he still lacks his literary limner. Almost the sole description of him now accessible is that left by the versatile Orpheus C. Kerr. There is embodied an analysis of that celebrated Gothic steed presented to this Orpheus by his maiden aunt and endeared to the saline affections of the mackerel brigade by several amiable idiosyncrasies. Of whom it is written: "The beast is fourteen hands high, fourteen hands long, and his sagacious head is shaped like an old-fashioned pickax. Viewed from the rear his style of architecture is Gothic, and has a gable end to which his tail is attached. His eyes are two pearls set in mahogany, and before he lost his sight were said to be brilliant." And more to the same effect, intimating a diet of shoe pegs for oats and saw-dust for millstuffs, save in the rare occasions when he could set his inflexible teeth into a hay bale with unadulterated joy.
