as American Beauties. It is probably tbe best bardy wbite Hybrid 

 Perpetual. 



Hybrid Teas may be called true perpetual roses. As yet 

 only about fifteen varieties are hardy enough for our climate but 

 they seem to be tJie future rose and may in a few years supercede 

 the Hybrid Perpetuals. 



La France is a silvery-rose color changing to pink. It is an 

 invaluable sort, the sweetest of all roses and one of the most 

 profuse bloomers. 



Augustine Guinnoiseau, a white variety tinted with flesh 

 color, is especially fine for forcing. 



Captain Christy, Kaiserin Augusta Victoria, Caroline Test- 

 out, Mme. Joseph Combet, Souvenir President Carnot, and 

 Liberty are among the best of this class. 



There are many parasitic diseases of the rose but only two 

 are very troublesome in this section. The common mildew is the 

 worst and a very rapid grower, causing the leaves to shrivel, 

 blacken and fall. Its growth is caused or encouraged by 

 draughts and sudden atmospheric changes, irregular or excessive 

 watering or extremes of any sort. Dusting the bush with flowers 

 of sulphur or spraying it with any standard fungicide will be 

 sufficient to control its growth. 



Black spot is a widespread fungus causing much loss among 

 rose growers. Yellowish spots appear on the leaves gradually 

 blacken and spread over the leaf and kill it, denuding a bush in 

 a very short time. The leaves and ground around the bush 

 should be well sprayed and all infested leaves gathered and 

 burned. Hybrid Teas are especially subject to this disease. 



The Rose Chaffer or Beetle is probably the worst insect pest 

 in this section. They appear about the second week in June and 

 live only thirty or forty days. They are not affected by solutions, 

 dusting with Paris green or hellebore may check their work, 

 spraying with water at 135° kills many, but hand picking is the 

 only eft'ective remedy, and a dish of kerosene is a good place to 

 drop them. 



The green fly or aphis is found on the end of shoots and 

 buds. They increase rapidly and will suck the vitality from a 

 plant in a short time. Tobacco in its various forms or kerosene 

 emulsion will at all times keep them off the plants. 



The presence of rose slugs is easily recognized by the 

 skeletonized appearance of the leaves. Hellebore, whale oil soap 

 or kerosene emulsion will destroy them. 



Thrips are very small insects on the jump most of the time. 

 Thorough syringing of the foliage is the best remedy against 

 them. White hellebore or whale oil soap applied so as to reach 

 the leaves from beneath will destroy them.
