In addition to these statistics which may be taken as conclusive on this question of the normal arrangement, I must point out that it is against all reason, and analogy from _all other_ mammals, to doubt that the normal arrangement is as I describe it. No hair-clad mammal either within the family of the Equidæ, or without, has any other arrangement on the under surface of its neck than what is here shown to be the normal one--a uniform uninterrupted slope from the head to the chest. There is also a feature of this greatly variegated piece of the horse’s coat under its neck, and that is that it is so highly variegated with diversity of pattern as to make it unlike any normal or natural structure or character in any animal. _That_ is not the way Nature does her normal work. It would be impossible to give illustrations of many of the patterns here found, though I have notes and sketches of a large number taken from the examination of thousands of specimens; so I have selected eight (Figs. 51, 52, 53, 54, 55, 56, 57 and 58) of the best representatives of these and the details of each are given under each figure. Effects of Pressure by Harness. _Second._--The next stage of the inquiry demands that one should show the patterns to be due to pressure. [Illustration: Fig. 51.--Roan cart horse, examined 25th September, 1914. On left side of middle line of the under surface of the neck a short reversed area three inches long, lying vertically--none on the right side.] [Illustration: Fig. 52.--Grey cart horse examined 25th September, 1914. Long central feathering (F) proceeding vertically upwards in middle line of neck from whorl (W) and ending in a crest (C) at the upper limit of region, through which the collar can move in active locomotion.] In the accompanying drawings the under surface of the neck and the chest of each horse is shown with the collar in place, the centre portion of which is cut out so as to show the arrangement of hair beneath, and some of the varieties are seen to extend for several inches above it. In considering this process one ought to watch the way in which the collar of a horse, as a rule, is seen to move up and down as he trots, for in most cases, except in cart-horses, the collar fits very loosely and is easily jolted upwards. This will explain why the patterns often extend upwards above the proper position of the collar, but it must also be remembered that _never_ have I found a pattern higher up in the middle of the neck than a loose collar can reach when jolted. (Close to the lower jaw there is a whorl or pattern often found which belongs to a different category, and is not to be confused with the patterns in question.) [Illustration: Fig. 53.--Brown hackney, examined 9th October, 1914. Small reversed area of hair lying under collar in middle line of under surface of neck, passing vertically upwards three inches long, in central position.]
