themselves. Only one of the strains 

 from other sources was unable to at- 

 tack young rooted carnation plants. 



On old carnation plants in the 

 greenhouse which were inoculated by 

 contact, even the carnation strains did 

 not cause a high percentage of infec- 

 tion. However, when plants growing 

 under these same conditions were 

 slightly wounded and then inoculated, 

 percentage of loss was very high with 

 nearly all the strains studied. When 

 conditions (temperature and moisture) 

 were favorable to the fungus, most of 

 the strains studied were able to infect 

 carnation plants as readily as the car- 

 nation strains themselves. In the ma- 

 jority of cases all strains were able to 

 cause damping-off of various seedlings. 

 There was a great difference in the 

 virulence of strains when inoculated 

 on the same host from which they had 

 been isolated and when inoculated on 

 other hosts. In a study of these ex- 

 periments the point that stands out at 

 first glance is the great variation in 

 the mortality of the plants when in- 

 oculated with strains from the same 

 host and when inoculated with strains 

 from other sources. 



Repeated observations in the green- 

 liouse and field have shown that a cer- 

 tain amount of the mycelium must be 

 present before the fungus is able to 

 attack and kill the plant. A small 

 amount of mycelium has always been 

 observed around a carnation plant in 

 the bench a week or more before the 

 plant showed any signs of being 

 diseased. In fact, a certain amount of 

 mycelium is always present in the car- 

 nation soil in the greenhouse, but it 

 is only when the temperature is high 

 that the fungus is able to attack the 

 plants. This explains why stem rot of 

 carnations is more severe during the 

 summer months than in the winter. In 

 the field similar conditions are neces- 

 sary to result in the infection of a 

 plant. 



MISCANTHUS SINENSIS (EULA- 

 LIA JAPONICA). 

 We have given over our cover page 

 this week to an excellent illustration 

 of this most useful of all the hardy 

 ornamental grasses. We have always 

 known it, as have most of our readers, 

 undoubtedly, as Eulalia japonica and 

 that name is liable to be the one by 

 which it will be best known in the 

 trade for many years to come. Ab- 

 solutely hardy, growing well in al- 

 most any situation and bearing beau- 



tiful feathery plumes in late summer 

 Eulalia japonica, in its several var- 

 ieties, is indispensable in the composi- 

 tion of grass beds in association with 

 Arundos, Pennisetums. etc., in mixed 

 borders or in "subtropical" bedding, 

 where it makes a graceful companion 

 and foil for the cannas. castor oil 

 beans and other broad foliaged sub- 

 jects.
