BULLETIN 466, U. S. DEPARTMENT OF AGRICULTURE. 



West Virginia and Indiana stand at the top in each determination' 

 the rest of the localities varying in their places. It is noted that in 

 each case the Ross lead number is higher than the Winton. The 

 average for the Winton number in the United States samples is 2.68, 

 with extremes of 4.95 and 1.85. Including the results from the 

 Canadian samples the average is 2.76, with the same extremes. 

 With the Ross number, the United States average is 3.34, with 

 extremes of 5.90 and 2.20. The increase in lead number by the 

 Ross method averages 0.58. 



Grouping the lead number by localities into divisions varying by 

 0.25 and placing the samples with these figures in such groups, the 

 results in Table XVIII are obtained.

In the total column of the Winton number, most of the sam- 

 ples have a number between 2.00 and 3.50. In some States 

 the variation is rather small; for example, New York shows 83 per 

 cent of samples between 2.00 and 2.74, Indiana 70 per cent of sam- 

 ples between 2.50 and 3.24 while in West Virginia no samples were 

 found with a number below 3.00. 



With the Ross number the largest percentage of samples falls be- 

 tween 2.50 and 3.99, New York showing 72 per cent between 2.75
