with the late Mr. Harris that crab roots will not answer for our 

 apple trees. They seem to be deficient in vigor, and the trees

 American plums when budded on Prunus pumila.

The wild rose bushes have long been infested with rose leaf 

 rust (Phragmidium subcorticiumj. This disease is especially de- 

 structive to the prairie wild rose (Rosa Arkansana) where attempts 

 have been made to cultivate it. Last summer this rust attacked 

 Rosa rugosa very severely, greatly injuring the bushes. Prof. Free- 

 man recommends burning the diseased part of the plant and spray- 

 ing with Bordeaux or ammoniacal copper carbonate. 



Among the new plants set out at the station this spring, are : 

 Viburnum tomentosum, Viburnum Pekinensis, Crataegus rotundi- 

 folia, Euonymus Maackii, and Ceonot'hus Virginiana — from Prof. 

 Green ; and Aconitum autumnale, Adonis vernalis, Alyssum sax- 

 atile compactum. Anemone nemorosa. Aquilegia Siberica, Campan- 

 ula punctata, Centaurea Carolinana, Delhinium grandiflorum, 

 Digitalis purpurea, Gaillardia aristata. Hibiscus, Alostheutos, Iris 

 christata. Iris flavescens. Iris Siberica, Lilium Canadense, Liliurn 

 tigrium splendens, Lupinus perennis. Lychnis diocia rosea, Papa- 

 ver nudicaule, Papaver orientale, Saponaria ocymoides — from H. S. 

 Horsford. 



The thanks of the station are due t'o Hon. A. J. Volstead and 

 to the National Botanical Garden for a large supply of rare seeds. 

 Many of these seedlings are doing finely.
