plowing. 
Out of 1,852 reports for walking plows 31 per cent use a 14-inch 
implement, 27 per cent the 12-inch, about equal numbers use the 
10 and 16 inch sizes, and only 19 per cent use other sizes than these. 
Nearly twice as many report a depth of 6 inches as are reported 
for any other depth, while nearly equal percentages are reported 
for 5, 7, and 8 inch depths. This fact may be accounted for by the 
general tendency of the human mind to employ round numbers in 
discussing magnitudes not exactly known. In this case the actual 
practice of farmers, if known, would doubtless cause these percentages 
to be so distributed as to increase that for 5 and 7 and somewhat 
reduce that for 6 inch depths. Teams of two horses are used by 
73 per cent of farmers. The 3-horse teams are used chiefly on the 
16-inch widths and on the 14-inch widths when plowing 7 or more 
inches deep. 
When the walking-plow data were arranged by widths with the 
depths averaged it was seen that the depth decreased as the width
