for Nevada. In counties whose missing records constituted a com- 
paratively small percentage of the total number of farms, the pasture 
acreage on the farms whose records were missing was estimated on 
the basis of averages for farms whose records were on hand. But in 
counties whose missing records constituted a very large proportion 
of the total number of farms the estimates were made on the basis 
of average acreage per farm for adjoining counties having similar 
agricultural conditions. There are, therefore, about seven counties 
for which the figures are estimates and possibly inaccurate, but for 
the remaining counties and for States and the United States the 
figures are as reliable as could be obtained by the method of enu- 
meration. 
Note 2. — By subtracting the figures for woodland pasture from 
those for the total woodland on farms, as reported by the census, a 
measure of the amount of land in woodlots not pastured could have 
been obtained if it were not for the difference in definitions. The 
census definition of woodland pasture is given on page 1, and 
woodland on farms was defined as follows: 
Woodland in this farm. (Give here land covered with natural or planted forest 
trees, whose principal value is in firewood, timber, or other forest products, which it 
will now or later yield.) 
Woodland pasture, therefore, according to the definition, includes 
a large territory of open pasture with scattered trees, and naturally 
this territory would not be reported as woodland. As a matter of 
fact the acreage reported for woodland pasture was, in many coun- 
ties, and even in many States, considerably in excess of the total 
acreage for woodland. Nevertheless, it was considered worth while 
to show in Table I the percentage of farm land not used for crops or 
pasture which was in woodland and in all other kinds of land not 
otherwise specified, with the understanding that these figures are 
only rough approximations. 
In the case of a few counties the reported pasture land is greater 
than the entire farm land, exclusive of land in crops, and in some 
others pasture land alone, as reported, is greater than the total 
land in farms. These discrepancies probably are due to the fact 
that in some cases, especially in the range States, the farmer would 
report as pasture a great deal of range land that he did not report as 
part of his farm. It was deemed advisable to let the reports stand 
as made, because there was no evidence on which to base any edi- 
torial revision. It will be understood, therefore, that these para- 
doxical returns are presented exactly as made by the enumerators. 
The following table gives the list of counties from which an excessive 
acreage in pasture was reported and the amount of the excess. This 
excess makes it obvious that the figures given for these counties in 
the column headed "All other farm land" were minus quantities.
