CENTRAL TRIAL STATION, ANNUAL REPORT. 83 



While we are able to combat both these diseases very sucess- 

 fully, by proper cultivation and spraying with Bordeaux, yet the 

 general belief among the most progressive experimenters today is 

 that we are most liable to get relief from these troubles by the 

 breeding of resistant varieties, and in our test of new vafieties 

 of potatoes we have in mind specially the resistance power of 

 these diseases. The varieties that have proven most desirable 

 during the past year, that is, have yielded a good crop of pota- 

 toes and had clean vines, are about as follows : California Rus- 

 sett. Golden Russett, Carman No. i, Early Market, Eureka Extra 

 Early, Acme, Rural New Yorker. Irish Cobbler and White Mam- 

 moth. 



About 800 seedling potatoes have also been raised this year. 

 These are seedlings from some of our most resistant kinds. Some 

 crossing work has been done with potatoes, the object of which 

 is to see what can be obtained by crossing our ordinary kinds 

 with Salanum Commersonii. 



About fifty seedling peonies flowered this year for the first 

 time. The most of these are four years old. xA.mong them were 

 a few kinds of considerable merit, which were much admired 

 at the summer meeting of the horticultural society. 



Among the newly introduced shrubs of desirable hardiness 

 we have raised the following for distrbution : 

 1,000 Crataegus rotundifolia. Fine hardy Hawthorn, desirable 

 for hedges and for single specimens. Thorns long, 

 flowers white, fruit deep red and freely produced. 

 3,000 Burning Bush (E. maackii). Best European form. While 

 this resembles in appearance the kinds we have formerly 

 grown it is much more fruitful. 

 50 Jersey Tea, Ceanothus americana. This wildling could 

 often be used in our shrubberies to advantage. 

 1,050 Vibernum tomentosum. Hardy flowering shrubs with 

 clusters of white flowers, followed by black fruit. A 

 valuable addition to our list of hardy shrubs. 

 137 High Bush Cranberry, (From Mts. of Pekin). Foliage 

 deep dark green color and deeply wrinkled, more grace- 

 ful in habit than our native form. 

 175 Russian Olive. Best small tree with whitish foliage; 



gives fine effect. 

 100 Norway Poplar. A fine poplar much like the Carolina 

 poplar, but a stronger grower. 

 45 Cut-Leaf Elder. American form : hardy vigorous and 

 graceful; not the common form and much more desir- 

 able. 

 1,000 Dwarf Golden Willow. Fine dwarf form. For shrub- 

 berries a decided improvement on the Russian Golden 

 Willow.
