 the standard most of the time. The lower part of the en- 

 graving shows the quality of two other cars, one for the 

 years 1893 and 1894 and one for 1895. In one case (C) 

 the milk is uniformly above the standard ; in the other case 

 (D) it gets slightly below more of the time, but not enough 

 to make any trouble for the dealer. 



The other engravings show the analyses of the milk of 

 herds. A, B, C and D (see p. 80) are the records of four 

 herds for three years. A is almost uniformly above the 

 standard, seven months of the time it was 14 per cent; 

 but the extremes may possibly be milk which was not 

 thoroughly mixed. B and O show in contrast two herds, 

 one of which is almost uniformly above the standard, while 

 the other is as uniformly below it. D is a herd showing 

 wide variations, running from 11.25 in May of 1892 up to 15 

 per cent in December of the same year ; this record suggests 

 the possibility of improper mixing, or of having an undue 

 proportion of new milch cows at certain seasons of the year. 



i^is a herd almost uniformly below the standard (see p. 

 81). G and //, as well'as J" and K, are interesting to study 

 together, showing the difference in different herds. G and 

 J" never got as low as 13 per cent, and G was over 15 per 

 cent five months of the year, while H and K were con- 

 stantly below 13 per cent, /is the record of another herd 

 uniformly above the standard, while L is almost constantly 

 below the standard. The upper line on page 59 is pecul- 

 iarly interesting, on account of the wide variations in the 

 quality of the milk of the herd, ranging from 11 to over 16 

 per cent. Another interesting fact in connection with this 

 herd is, that two analyses show that the milk was watered, 

 a complete analysis for the month of May being 7.5 of solids 

 not fat and 3.5 per cent fat. In June the analysis was 7.78 

 solids not fat, plus 4 per cent fat, making a total of 11.78. 



E is the story of a herd from July, 1892, to November, 

 1894, the milk of which was more constant in quality, and 

 was, with one exception, on the standard or above (p. 59). 



This interesting field of investigation could be carried 

 much further, but enough has been presented to show that 

 some herds are always above the standard, some almost
