and the front one, maybe, some three inches lower. 
The thicker you make your wall of turf the better. 
It ought to be quite two turfs thick to keep out 
the frost. Sometimes, too, you may heap up soil 
and leaves outside in a bank, which greatly adds 
to the warmth. 
I have heard of some boys making a stout sort 
of boarded or brick wall, using simply for it any- 
thing they could get, and driving in posts all 
along for security — and then making a double wall, 
they filled in the whole space between with a bank 
of loose earth and leaves. This is a very easy and 
effectual plan when people can get old boards. The 
roof should always rather overhang the sides ; be- 
cause if the walls get damp it is a poor look-out for 
the plants inside, which soon get damp and mildewy. 
I have seen these pits too done with wattling or 
rough basket-work, with the holes, when there 
were any, stuffed up with moss, and the sides 
painted over to preserve them better — roof, cover, 
and double walls, all were done in this way ; and 
I certainly think it made the neatest-looking pit 
that could be. 
The floor of the pit should be very dry, and a 
good thick layer of coal-ashes and small cinders is 
the best thing to put in it for the pots to stand in.
