hardy. The past two winters the tips were badly frozen. Abundance 

 makes a very late terminal growth. Sheuse apricot winter kills even 

 more so than the above. The past two winters have been unusually mild 

 and it is fair to presume that the Abundance plum and Sheuse apricot are 

 beyond their latitude anywhere in Minnesota. 



Seedling Sand Cherries. — From a promiscuous lot of sand cherry pits 

 received from South Dakota and northern Minnesota, planted in 1890, at 

 least twenty distinct variations (better than the type) in fruit, size, color 

 and quality were produced. As no attempt was made towards selection in 

 this first lot of pits planted , it demonstrates the great variability of the sand 

 cherry under culture, and as we have in some of our seedlings many desir- 

 able qualities, it gives us hopes that in a few years varieties will be pro- 

 duced which will in many respects equal our best cultivated varieties of 

 cherries. Budded on native plum our plants were loaded with fruit, 

 while those on their own roots fruited sparingly. 



Budded Roses.— It may not be generally known, but our native wild 

 rose, Rosa blanda, is one of the best stocks obtainable in the Northwest 

 as a stock upon which to bud any or all of the Hybrid Remontant, Hybrid 

 Tea, Hybrid Noisette, Tea, Bourbon and Noisette classes. 



For the past five or six years we have been experimenting with roses on 

 their own roots, budded low on Manetti, and worked as tree roses on native 

 stock. The difference in favor of the native stock was observed by 

 hundreds of visitors who saw our roses last summer. We have plants so 

 worked, that are six years old, and they are just as healthy as can be. The 

 union in nearly all cases is smooth and perfect. Dwarf and weak growing 

 varieties are stronger and healthier than on own roots. From a row con- 

 taining Hermosa, Madame Pierre Oger, La France, Madame Andre 

 Duron, Queen of Queens, Reme Marie Henrietta, Bouquet D'Or, Celine 

 Forestier, Madame Celeste, Etoille De Lyon, L'Abundance and Madame 

 Georges Bruant we were able to cut roses every day from June 12th to 

 Nov. 1st without a single exception, with here and there a magnificent 

 bloom of Hybrid Remontants during the entire season. 



As a rule all roses of less than a very vigorous growth do better, blos- 

 som more freely and stand the winter better when worked our native 

 stock than when budded on Manetti or on own roots. 



Such varieties as Hermosa (bourbon), La France (hybrid tea), Reine 

 Marie Henriette (climbing tea), are wonderfully improved in size, color 

 and freedom of bloom. We find no trouble from suckers after the first 

 year, and know of no reason why roses so worked should not be long lived. 



CROSSING AND HYBRIDIZING. 



There are about fifty very promising seedlings of vites riparia fertilized 

 by Lindley and Moore's Early, and as many more rose seedlings. Rosa 

 blanda fertilized by various remontants and bourbons, demonstrate that 

 as far as constitutional vigor and beauty of foliage is concerned the 

 union is a beneficial one. At least two hundred apparently successful 

 crosses and hybrid crosses were made and well developed seeds procured 

 of the following record: 



Ribes Floridum crossed with Danish black currant. 



Prunus pumula " • Miner plum. 



Ostheim cherry " Prunus pumula. 



New Ulm plum " Hungarian plum.
