least four inches of soil, and put on the sashes. Place a 
thermometer in the bed, and await results. In the course of 
two or three days the beds may be trusted with seeds. The 
thermometer ought not to register much over 70° ; if the heat 
is greater it is better to delay matters for a few days. 
There is a possibility of burning the seeds by putting 
them too soon in a new hot bed, especially if the sun shines

the young plants appear above ground. ‘The seeds may rot 
in the ground if over-heated. It is necessary to air the beds 
slightly from the start, even in cool weather; and to give 
more and more air as the plants increase in size and as the 
season advances. 
There ought to be a thermometer kept in the hot bed, 
and the day heat not allowed to get above 70 degrees. The 
night heat ought not to fall below 50 degrees. Shutters, 
mats, carpets or litter will make it easy to keep young plants 
warin at night.
