and the Window Greenhouse. 61 



is the proper treatment to give your little greenhouse. 

 I wish you to consider what I have said about it 

 earnestly. I have told you in as plain words as I can, 

 and I hope you will follow the directions I have given. 

 Read them over often till you have a clear idea what to 

 do, and there is no fear of your being unsuccessful in 

 its management. You will notice I have not said 

 any thing about winter treatment for your greenhouse. 

 This is hardly necessary, for, unless you can heat it, 

 the plants must be all brought inside the window at 

 the approach of winter. Here I will tell you a very 

 simple contrivance by which you can have your plants' 

 in your greenhouse for a considerable part of winter, 

 when no severe frost is in the air. If the night is 

 frosty or cold, fiU a stone jar — what is commonly called 

 a greybeard wiU do — full of hot water and place it 

 inside your greenhouse after sunset. Have another 

 hot one to replace the cold one at bed time. This 

 warms the greenhouse nicely and keeps out a moderately 

 keen frost, if at the same time you have a bit of old 

 carpet or such like material to put on the roof outside. 

 This is a very simple way of heating by hot water. 

 And, in fact, you would benefit your plants a good deal 

 by doing this on any very cold night during the fall of 

 the season and the early spring. If you wrap the 

 greybeard in two or three folds of- flannel or any old 

 woollen stuff the heat will be economised and last some 

 time longer. 



I had intended to say a few words in this chapter 

 about insects and their prevention and cure, but giving 

 them a short one to themselves will make it plainer for
