nual species succeed in common garden soil, and are read- 

 ily ncreased by seeds, which should be sown in May. The 

 half-hardy sorts should be reared on a slight hot-bed in 

 April, and planted out in May. The common Marigold is 

 very brilliant.

 border. When sown thus, it must be in May, and these will 

 come into flower in July, a month after those turned out of 

 pots in a forward state. This flower ought, of course, to be
