NIGHT-SOIL. A very powerful manure, composed 
of human feces and urine, especially when taken from 
earth-closets, as all the fertilising constituents are 
saved, which is not the case when collected in tanks 
with large quantities of water present. Being so rich 
in plant-food, Night-soil should be applied to the soil 
in comparatively small quantities, particularly to growing 
crops, otherwise injury may follow its application. 
NIGHT TEMPERATURE. Mauch of the success 
or failure of the gardener who has hot-honses or frames 
under his charge depends on the Night Temperature 
maintained. It is an accepted fact that the temperature 
in all such structures should be lower at night than 
during the day. Plants, like animals, must have periods 
of rest to make a. sturdy, healthy growth; and if the 
Night Temperature is not allowed to fall below that of 
the day, the growth of plants, Vines, or other frnit- 
bearing trees becomes weak and thin, followed by 
ill-health. Again, high Night Temperatures induce an 
attack of Red Spider, Thrips, and a host of other animal 
and fungoid pests, the dry heat usually found therewith 
being specially favourable to such enemies.
