RAISING NEW VARIETIES. 181 



ural fertilization, if we will but pattern after 

 nature and carefully study the laws of cause and 

 effect. 



Though there is a difference of opinion 

 respecting the quahty and finish of the roses 

 likely to result from manual f ecmidation, all prac- 

 titioners admit that there is a certainty by this 

 method of obtaining a product distinctive in char- 

 acter, which is of itself a sufficient inducement 

 to encourage our best efforts in this line. But 

 the truth is, so few crossed roses have been 

 raised, compared to the number from natural 

 selection, that we have learned very little about 

 the successes and failures that have attended the 

 operators in this field of study. Yery few of 

 those who have engaged in this work have given 

 us any information that will be of use to those 

 who wish to experiment. It seems to me, the 

 lack of finish and the delicate constitution, averred 

 to belong to varieties raised from artificial crosses, 

 come from bringing together roses of different 

 types, too widely separated in character to blend 

 well. I believe roses belonging to the same type 

 will always cross with good results. Those who 

 wish to practice this art will do well, therefore,
