Should your plants of cabbage, lettuce, beets or 

 cauliflower by any chance get frozen, do not give 

 them up for lost, for the chances are that the follow- 

 ing simple treatment will pull them through: In 

 the first place, shade them thoroughly from the sun ; 

 in the second, drench them with cold water, the 

 coldest you can get — if you have to break the ice 

 for it, so much the better. Try, however, to prevent 

 its happening again, as they will be less able to resist 

 subsequent injury. 



In hot weather, where watering and ventilation 

 are neglected, the plants will sometimes become in- 

 fested with the green aphis, which under such con- 

 ditions multiplies with almost incredible rapidity. 

 For treatment in this case see page i6i. 



Hardening off : For five days or a week before 

 setting plants in the field they should be thoroughly 

 hardened off. If they have been given plenty of air 

 this treatment will mean little change for them — 

 simply exposing them more each day, until for a 

 few nights they are left entirely without protection. 

 They will then be ready for setting out in the open, 

 an operation which is described in the next chapter.

 of plants out-of-doors, for second and for succes- 

 sion crops, such as celery and late cabbage. Select
