the highest amouut of success, fresh sand should be

SUMMER PROPAGATION. 
The details and the principles involved in this very 
important method of propagation are the same as in 
Winter propagation, the only difference is the bottom 
heat supplied by the pipes and boilers in the Winter, has 
in Summer to be obtained from hot beds of fermenting 
manure. These bedsare usually made during the months 
of May, June and July, in some out of the way place, 
filled in with stable or horse manure that will heat to a 
depth of from twenty-four to thirty inches; it must be 
firmly beaten down, and about four inches of sand of 
quality as before directed, placed on top of this, which 
also must be made as solid as possible by beating it with 
a mallet or brick ; the sash should slope to the north, and 
posts must be put in the ground all around the bed so as 
to nail some slats across to support the shading which 
must be tacked on all over the bed, so as to completely 
obscure the scorching rays of the sun we have at that 
season of the year. An opening in the shading may be 
left on the front and north side of the bed, where you 
may pass in and out to attend to the watering and venti- 
lation of the cuttings, as the sun will never strike the 
bed from that side. Have the shading sufficiently high, 
so that you can walk under it around your bed, as it is 
more convenient and allows of a greater circulation of 
air between the shading and the glass, which will result 
in keeping the top or atmospheric heat less than the bot- 
tom heat, or that given by the manure. If the top heat 
should by any mishap be kept in advance of that‘at the 
base of the cutting, suceess can never be obtained. It 
may seem strange to many, the necessity of making a
