in sprint.', shake them out, prune them to an eye or two, 

 cut out thi' ai;;ul parts, repot tliem, and presently they 

 will start to Kiuw again. They maybe gradually har- 

 dened, plunged outdoors and grown in the full sun dur- 

 ing summer; giving them a shift during growth if extra 

 luxuriance is desired. If bench culture is desirable, 

 plants may be turned into the ground from 4-inch pots, 

 or even from the propagating bed, grown until the end 

 of August or later southward, the leaves stripped from 

 all the stems but the upper foot or so, lifted, and laid 

 flat on the benches, with a bushel or so of good soil over 

 the roots and about an inch over the benches in the 

 spaces. The next rank of plants may have their tops 

 laid well over the roots of the first, and so proceed until 

 all are planted. The ends soon turn up as growth starts, 

 and the heads are very large and fine with suitable 

 temperature and attention. Soiiietiiiies mealy bug gets
