The reason for dis- carding the shorter records in making tabulations was to avoid pos- sible error due to the use of SUch records. The possible error due to a ii- -i records, however, is probably negligible, as average yield, cost, and income proved to be about the same per cow-year' v, hen the records of all COWS On test Were included as when only the ords of those on te-i L2 months were included, (^cr Table L) This indicates thai the herd and ae ociation summaries as now ob â to 1 able Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States.
