Extraordinarily Successful Result of Cross Pollination 



to remain in boxes of finely sifted sand during the Winter, the boxes 

 to be buried several inches below the surface of the soil out of doors. 

 In removing the seeds from the sand previous to sowing, use a sieve 

 with a small mesh; empty the sand (which is likely to be wet) into 

 this, and force the sand through the meshes with the aid of a stream 

 of water from the hose. The seeds should then be sown before get- 

 ting dry. Care must be taken to remove them from their Winter 

 quarters before vegetating, which they are apt to do, even when they 

 are deep in the soil, as soon as the temperature of their surroundings 

 reaches 40 degrees. Another method of treating Rose seeds, especially 

 those which ripen as a result of cross pollination, and one, which 

 if carefully done results in quick germination, consists of cutting off 

 one end of the achene a little at a time until the seed is partly ex- 

 posed. This can only be done with great care and with the aid of a
