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.

1 Determinations not made on one sample. 2 Two not made. 
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
