His influence is also felt in some of the great houses and surrounding gardens which he was responsible for architecturally and aesthetically. Our two weeks which will include Press Day at the Chelsea Flower Show, will include visits to some of these Treasure Houses, with private to urs conducted by the owners or head gardeners, as well as tours of some small er and more private estates, little known to the general public.

Lost anD FOvfJ1D: Forma{ GarDens of Eng{anD June 17-July 2, 1987 Come to the mysterious wo rld of England's 'Lost and Found Formal Gardens; ranging from the grandeur of Powis Castle in Wales, to the sundappled mystery of Melbourne. We'll see the strange emblematic topiary garden at Packwood House in Warwickshire, and the coziest Thdor & Stuart manor houses. A special tour with Graham Stuart Thomas of his """"""""''''-'' wo rld famous old rose collection at Mottisfont Abbey is schedul ed. Although most of the ~(19!!rJi magical gardens of Renaissance and 17th-century England were swept away by the· improving hand of Capab ility Brown, Humphrey Repton, and other great exponents of the English 18th-century landscape school, eno ugh traces remained to inspire a revolution in 19th-century England. Under the influence of Sir Walter Scott, many an old garden was revived and revised . Through such gardens, we'll be able to trace the little known history of England's fantastic formal gardens.

GarDens of the Riviera anD BurgunD;9 September 19-0ctober 3, 1987 This delightful fall trip to France will enchant all lovers of roses as well as those of you who thrill at the thought of the Riviera and of Burgundy. Under the guidance of Richard Hutton, our leader and President of Conard-Pyle/Star Roses, we will tour some of France's most important gardens and nurseries. Among our hosts will be Selection" Meilland, one of the world's foremost rose breeders as well as many private individuals who will open their gardens to us. We will spend one week in the south of France touring the Riviera from Monaco to Nice and Antibes. We'll spend our second week aboard the luxurious hotel barge Jan ine' floating through Burgundy's rich and varied countryside visiting nurseries and gardens as well as some of the vineyards so busy at this harvest time of year.

Ken;9a anD East Africa October 14-31, 1987 Our trip to Kenya should delight and surprise those who are interested not only in horticulture but also in the wildlife, ecology and geography of East Africa. These two weeks offer an exciting and adventurous opportunity, unusual in scope, content and variety. We will visit a wide range of habitats and vegetation zones where both flora and fauna thrive. After a brief stay in Nairobi, we are off on our horticultural safari, journeying north to the Aberdare National Park, a lush verdant region typical of an equatorial forest ecosys­ tem. We will cross the Equator en route to Samburu Game Reserve, a semi-arid landscape, and continue on to the multi-vegetational zones of Mt. Kenya and our visit to the luxurious Mt. Kenya Safari Club. An exciting adventure follows with three full days of game viewing in the Masai Mara, Kenya's finest game reserve before concluding our safari in Lake Naivasha touring private estates and gardens.
