Our tour leader will be Mary Mattison van Schaik. Mrs. van Schaik, now a Vermonter, lived in Holland for 18 years and has owned a bulb importing business for 30 years.

Traveling through remote and breathtaking scenery, we will tour th e Isle of Gigha, Crarae Woodland Gardens, Inverewe and Inverness. We will be entertained in private homes and castle gardens. In Edinburgh we have the opportunity to explore the city at our own pace and to be entertained by some of Scotland's most enthusiastic and privileged horticulturists. We are again fortunate to have Everitt Miller, form er director of Longwood Gardens, as our leader.

AMERICAN HORTICULTURIST. 7 1985 Summer Intern Profiles: ( Brian Little and Karl Stromayer

orticulture entered Brian Little's life when his father H accidentally backed the family car into a neighbor's crape myrtle. "We walked into Mr. Forster's house to explain what had happened, and I was just overwhelmed by all the house plants," Brian said. It turned out Mr. Forster, whom Brian came to call Grandpa, wanted to get rid of the crape myrtle anyway, and Mr. Little's car had done him a favor. "We were good neighbors after that," Brian recalled, and Mr. Forster began to teach seven-year-old Brian all about outdoor gardening, while his wife gave Brian lessons in caring for house plants. Brian learned to propa­ gate African violets when he was eight years old, working with Mrs. Forster's hundreds of windowsill­ grown plants.
