and that rest is induced in a tropical climate by drought, in the same way as low temperature in our 
own country suspends vital energy : therefore Orchids must be subjected to the usual seasonable changes 
of rest and activity. Rest is induced by withholding moisture from their roots, and partly from the 
air, and this state of things may be considered to represent their winter. Spring should be imitated 
by gradually reviving vital energy by increase of moisture, first to the atmosphere, and afterwards to 
the roots or soil, accompanied by a proportionate increase of temperature : this period of their 
growth should be very slow. Summer must be represented by a greater increase of both heat and 
moisture j partial shade should also be resorted to, to bring the energy of the plant into full force.
