to proceed if we do not wish to reproduce the 1 Jacqueminots ' and 1 Victor 

 Verdiers ' to infinity and keep on going round in the same well-known 

 defective routine for ever. 



The fine yellow Roses which had up to the present time refused to be 

 fertilised by different species have been conquered. Taken as seed-bearing 

 plants they refused to be crossed ; but used as pollen -bearing parents 

 they have already produced offspring which promise well for the future. 



Quadroons. 



We make use of the word " quadroon " to some extent to attract atten- 

 tion, because this substantive is not used either in horticulture or in botany. 

 It is employed in natural history to point out the degree of relation in the 

 crosses between the white race and the black. 



White and black give mulatto. 



White and mulatto give morisque. 



White and morisque give quadroon. 



White and quadroon give mameluke. 



White and mameluke give saccatra. 



White and saccatra give mixed breed. 



Now, with Roses, it is very seldom that one obtains a remarkable 

 variety at the first attempt ; indeed it is generally not until the third or 

 even fourth or fifth fertilisation that one has the good luck to produce 

 striking and distinct subjects. 



I have tried for a long time to obtain what are now called Hybrid 

 Perpetuals, a perfect chaos into which the French Society of Rose-growers 

 might well impart a little order. I began with small perpetuals, which 

 were hardly perpetual at all, to arrive at real perpetuals, some of which also 

 were very little so. 



Rose-growers who would like to get on faster, and obtain more rapidly 

 Roses arising from u known patterns " and having new colours, ought to 

 know that they should not set to work on two single-fiowered types, but 

 choose a new type and a quarter-bred cross, that is to say a Hybrid 

 Perpetual, or a Tea, or l>engal Rose, etc. ; that is, a perpetual Rose that 

 is quite double. 



Certain experiments which I have made in crossing two types with 

 single flowers, or not perpetual, induce me to warn professionals, who as a 

 rule have no time to sjmre. 



This question of hybridisation in the genus liosa requires to be more 

 closely examined ; but, not wishing to prolong these remarks indefinitely, 

 I hope later on to take up the question in detail.
