Excerpt from The Dispersion of the Gipsy Moth, Vol. 119 The dispersion of the species, as treated in the above mentioned report, was considered as local and long distance. The former condition was brought about by egg clusters being broken and scattered by birds or other animals that frequent infested trees. Clusters were also carried on driftwood (see pi. I), and those deposited on leaves (see Pl. II) were so stimes distributed by the wind. The caterpillars were occasionally found clinging to the bodies of animals or to the clothing of persons who had visited infested places and were carried short distances in this way. Many colonies were established in remote districts by the carriage of the larvae on vehicles, and egg clusters were sometimes transported on cordwood or lumber products shipped from infested forests. (see Pl. III.) The distribution of caterpillars upon vehicles was con sidered so important when the gipsy-moth work was begun in 1891 that inspectors were stationed along the main highways to stop and examine all vehicles and to destroy any caterpillars found before allowing them to pass out of the infested area. This precaution was entirely warranted in view of the discovery that many farms had become infested by the transportation of caterpillars on vehicles. Places infested in this manner, however, were usually occupied by milkmen, peddlers, swill gatherers, or persons whose business caused them to drive regularly to and from the city during the summer, or to neighborhoods that were badly infested with the gipsy moth.

Excerpt from Dispersion of Gipsy-Moth Larvae by the Wind Many investigations Of various sources of Spread Of this insect were conducted during the early nineties by Forbush and Femald and published by, the Massachusetts State Board Of Agriculture in 1896. It was found that frequent teaming in and Out Of the original infested areas (m'edford, boston, and towns closely surrounding) by vehicles transporting larvae that dropped from infested Shade and roadside trees was largely responsible for the general local Spread during those years. It was also suggested that the larvae were Occasionally trans ported by the wind to distances Of perhaps 100 yards, but no further Observations were made. At that time to substantiate this theory. Numerous ways and means Of local spread, such as by birds, animals, and man, are treated in this valuable report.
