1. 4 places over 2 because:

a: her decided advantages in frame and body capacity. She has more depth, spring, sweep and openness about both her fore and rear ribs. She is also deeper and wider through her heart girth, fuller through her crops and harder down her top line.

b: she is also:
more desirable in her slope from hooks to pins, noting the high pins on 2.

c: and
she has a higher rear udder attachment with more bloom throughout the top and a more clearly defined udder cleft.

I admit that 2 is:

cleaner through her hocks, standing with her legs more squarely beneath her, having a smoother blending fore udder attachment and more desirable turn to her rear udder.

2. Next, in my middle pair, I place 2 over 1 because:

a:
of her overall advantages in balance, style, udder and feet and legs. She has more correct set to her leg, faulting 1 for being to sickle, stands with her legs more squarely beneath her and is cleaner through her hocks.

b: In addition, she is:
showing more dairy character, where she is more clean cut and feminine about her head and neck, longer and leaner through her neck, is more sharply chisseled over her withers, more clean cut over her hooks and pins and more incurving in her thighs.

c: Further, 2 is
smoother from neck to shoulder and shoulder to barrel and is harder on down her top line. She also carries her udder higher above her hocks and is smoother about her fore udder attachment.

However, 1 has:

less quartering to her udder and has more bloom throughout the top of her rear udder.

3. Finally, 1 places over 3 because:

a:
of her tremendous advantages in udder and body capacity. She has a much deeper udder cleft, which carries throughout the top of her rear udder, and has her teats placed more centrally beneath her quarters. She also has a much higher, stronger rear udder attachment.

b: She is also:
much wider through her heart girth and has more power and strength throughout.

c: Moreover, 1 is
smoother through her front end and holds her elbows tighter to her body wall.

I realize that 3 is:
much more refined, more clean cut and angular cow throughout

But I'm placing 3 last, because:

a:
she lacks power and strength

b: and
youthfulness of udder to merit a higher placing.

to place any higher in this class.

These are my reasons for placing this class of Brown Swiss 4 year olds 4-2-1-3.
