5	Showing F.C. Reimer traveling while investigating pears in northern China - 1919
6	Reimer’s Trip Objectives Search for pear species with resistance to fire blight for use as rootstocks Determine localities where large quantities of seed could be obtained for rootstock production Determine whether wild pear species of Japan were also present in China Determine whether undesirable species occurred in proximity to desirable types – and whether they might hybridize
7	Additional Objectives Make a systematic study of “Oriental” species and attempt to determine whether they were valid species, subspecies or hybrid species. Secure information about horticultural value, geographic distribution and environmental requirements of the various species
