22 A GUIDE TO FLORICULTURE. 



structive to germination, for instance, if a pan oi seeds bo 

 sown and covered with glass, one half with red and yellow 

 laid one on the other the seed would not germinate, while 

 the other half being covered with violet the seed would ger- 

 minate quick ; reverse the glass and the result would be the 

 seed would come up, and those up on the other half would 

 cease to grow. This in some measure corresponds with 

 seeds sown on the surface and exposed to the sun will not 

 vegetate, for a portion of the sun-light which produces the 

 organs of light diffusing its warmth, is destructive to the 

 first process of the vegetation of seed, but if removed into 

 the shade or darkened vegetation then commences. These 

 experiments are worthy of notice, and may prove of use to 

 those fond of experiments. It was attributed to Mr. Hunt 

 as the first person that tried these experiments on the ger- 

 mination of seeds with colored glass, in 1840. I find the 

 late Dr. Morechini, of Rome, made the same in 1838. The 

 late professor of Botany is entitled to the credit of his re- 

 searches. 



TRANSPLANTING. 



Transplanting is the art of removing seedlings from the 

 nursery-bed into the open ground ; this operation is easier 

 effected in the spring than at any other time through the 

 year, as the spongiolis of seedlings will strike fresh root 

 easier. Transplanting should be done after a shower or in 

 a cloudy day towards eveningy and great care should be
