A map of the areas traversed by Dr. Harold P. Olmo in 1948 during a Central Asian germplasm acquisition trip. Straight lines represent travel by air, dashed lines travel by automobile, horse and burro, and dashed lines broken with dots are travel by train. He spent one year travelling over 12,000 miles while collecting 775 extremely valuable accessions of fruit and nut varieties in Iran, Afghanistan and Pakistan. He collected both seeds and cuttings during this trip, which were sent back to the USA at regular intervals.
