Miller Library News Spring is the perfect time to browse through seed and garden catalogs, and we now have over 300 catalogs on file in the library for browsing and reference. There’s also an “Exchange Basket’’ full of donated copies and extra copies which you may feel free to take and keep. Thanks to a gift from Pendleton Miller for book purchases, many exciting new books are being received, such as Sandved’s Leaves, Collector’s Alpines, and The World of Bamboo. Many other individuals and plant societies have also made donations. We have recently received Fred Galle’s new Azaleas, a gift of the Lake Washington Garden Club in memory of Mrs. Gladys Corneliussen. The library could use a few additional volun- teers for the summer, both for specific pro- jects and for general assistance. If you have an interest in seed catalogs, computer typing, or processing new books with labels and plas- tic covers, and if you can volunteer at least twice a month, please contact Laura or Val- erie at 543-8616. Try Something New for Spring Get to know the Center from the inside. Our reception desk needs volunteers to answer the phone and assist the secretaries. It’s an excellent way to become familiar with our operations here and at the Washington Park Arboretum. Stay tuned for volunteer oppor- tunities in the new Washington Park Ar- boretum Visitor Center. With the demolition of the old Arboretum offices and the creation of the new CUH facil- ity, our need for volunteer historians has grown. We have historical photos, slides, drawings, and artifacts that need careful sort- ing and compilation. One or more volunteers who can contribute this valuable service are eagerly sought. For further information or an appointment, call Van Bobbitt or Becky Johnson at 543-8616. Plant Sale Free catalogs for the spring plant sale of the Arboretum Foundation Unit council are avail- able. The 39th annual sale, to benefit the Washington Park Arboretum, will be held there May 7 and 8. Catalog users can pre-order until April 18, from a listing of hundreds of choice garden plants in a wide range of sizes and prices. A $5 deposit will hold the order for pick up the first day of sale.
