REPORT OF MR. N. WOLVERTON Z'Zl 



SESSIONAL PAPER No. 16 



A new cross-bred seedling was received in the spring, of 1906, from Prof. Hansen, 

 of South Dakota. It is a cross between the Jessie and the Manitoba wild strawberry. 

 The growth was vipiroiis and the few berries allowed to ripen were fine and large. 



PLUMS. 



During past j-ears many cultivated varieties and seedlings have been tested, bnt 

 in nearly all cases the fruit is too late in ripening. 



The Native Manitoba plum is probably the stock from which our future plums 

 will come. Persistent planting of pits and weeding out the poorer sorts will no doubt, 

 in time, produce excellent plums, which will be early and hardy. 



GOCSKBERRIES. 



The winter was very hard on this fruit. Of twenty-five varieties under test the 

 majority were winter-killed and there was very little fruit. 



CURRANTS. 



Thirty-three varieties of red, white and black currants are under test. The crop 

 this year was light. Unfortunately, just at our busiest time, when it was impossible 

 to give them attention, the currant worm did serious damage and reduced the crop to 

 almost nothing. 



Of the red currants the following are among the best in yield and quality: 

 ^■)mona. Large Red, New Red Dutch and Red Dutch. 



Of the white, the following: "White Cherry, Verriers White and Large Wliite. 



Of the black, the following : Sterling, Standard and Star. 



THE ARBORETUM., 



No additions have been made to the Arboretum during the year. Many trees and 

 shrubs have so increased in size that much thinning must be done before adding many 

 other new varieties for testing. 



The Russian poplars on the side hill are still further damaged by the fungus 

 which is weakening the stems. Quite a few have been broken by the wind and have 

 become unsightly. 



Bnt few of the cottonwoods are left. The leaf fungus is killing them one by one. 

 On the low lands they do well. 



Especial notice is called to the following hardy, handsome and very desirable 

 ornamental trees : 



Manitoba Maple {Acer Negundo), excellent in all situations; Native Paper or 

 Canoe Birch (Betula papyrifera) ; American Mountain Ash (Pyrus Americana) ; 

 White Spruce (Picen alba) ; Balsam Spruce (Abies balsamea) ; Tartarian Maple 

 {Acer tataricum.) ; Ginnalian T^lnple (Acer tataricum Ginnala) ; Sharp-leaved Wil- 

 low (Salix acutifolia) ; Laurel-leaved Willow (Salix pentandra) ; Siberian Berried 

 Cvab (Pyrus haccafa) ; American Elm (Ulmus Americana). 



The following hardy and attractive flowering shrubs are especially recommended: 



Siberian Pea Tree (Caragana arborescens, O. frutesceni? pendula, C. pygmaea) ; 

 Native Hawthorn (Crataegus coccinca) ; Sharp-leaved Cotoneastor (Cotoneaster 

 acutifolia) ; Common Cotoneaster (C. integerrima) ; Bush Honeysuckle (Lonicera 

 spinosa and L. tatarica) ; Neillia (Neillia opulifolia) ; Philadelphus or Mock Orange 

 ( Phihdelpli v.s grandiflora) .

 JosiTcaea). 



PHILADELPHUS (mOCK GRANGE). 



This beautiful shrub was for many years past considered too tender to be success- 

 fully grown in Manitoba, the wood killing back to the ground each winter. An ex-
