Q: I am planning a trip this month to the Yellowstone National Park, the Grand Tetons and Jackson Hole. What will the weather be like?
A: Take your sweaters, long johns and a good slicker.
The normal daily maximum in the region in October is 56 degrees, with the minimums at 26. However, those temperatures are for the parks' lower elevation. Take another 5 degrees off those numbers if you are planning to climb or hike.
Normal monthly precipitation there at this time of the year is 1 inch, compared with 2.2 inches in June and compared with 3.5 inches in New York. Precipitation at the higher elevations is greater.
On the bright side, there is a 60 percent chance of sunshine, with the number of clear days averaging 15.
Q: I am interested in William Morris and the Arts and Crafts movement in England. Do you know of any tours devoted to his work?
A: Hilton Hotels in England runs a number of special-interest weekends each year, and this year five were devoted to William Morris, a Victorian poet, artist, craftsman, designer, social reformer and printer.
The Hilton weekends, consisting of talks and tours, start on Friday night and finish on Sunday. For example, a weekend at the Hilton National Coventry, about 100 miles north of London, was led by a member of the William Morris Society.
On Saturday there was a guided tour of the Pre-Raphaelite rooms in the Birmingham Art Gallery and a visit to Wightwick Manor, which contains many original Morris wallpapers and fabric, William de Morgan ceramics and Pre-Raphaelite pictures. This was followed by a champagne dinner at Deene Park, a medieval manor house with extensive 19th-century additions. On Sunday there was an illustrated talk about Victorian needlework at the hotel.
Six to eight Morris weekends will be held next year, but no dates or prices have been set. This year's events cost $234 to $262 a person, calculated at $1.50 to the pound.

Or, contact Richard Tames, a registered London Tourist Board guide and author of a book on Morris. His fee, for groups of up to 20 people, is $375 a day, plus transportation and admission. He will be conducting a Morris study day at the Victoria and Albert Museum in London on Oct. 21. Reservations should be made; the fee for the day is $75, including lunch.

Independent travelers might want to visit the William Morris Gallery, in the East End of London, home to the Morris family from 1848 to 1856. It houses extensive examples of his work.
The William Morris Society, Kelmscott House, 26 Upper Mall, Hammersmith, London W6 9TA, England, publishes a journal and newsletters. Its activities include talks, museum visits and social gatherings. Membership is $20 a year.
