50 Alpine Plants. 
a hole. 12in. deep, with 2in. of drainage at the bottom. 
Prepare a compost consisting of retentive loam, 
leaf-mould, and broken limestone, in equal parts, 
together with a few pieces of hard peat in 2in. cubes. 
Fill in the hole to a depth of 8in. with the prepared 
compost, and then plant close to the rock, so 
that the root almost touches it ; level up with com- 
post, and finally surface with a little fine lime- 
stone. In March top-dress with a little loam and 
limestone. 
Erigeron trifidus (N. America). 
Plant in a well-drained, sunny place on the flat, 
facing south-east, in equal parts of loam, leaf-mould, 
and grit. In spring, and again in autumn, top-dress 
with the same compost. 
Eritrichium nanum (Alps).

Alpine gem may be much reduced if the following 
instructions are carefully observed. A nice, sunny 
fissure should be selected on the rockery, not too high 
up, and yet where the plant will be close under the 
eye, in such a position that moisture can be given to 
the plant during the growing season without the 
foliage or face of it being damped at all, and where it 
can be kept perfectly dry from September until 
January. During these months it is quite dormant, 
not beginning to grow until towards the end of 
January, and even then no water must be given for 
fully a month after signs of life begin to appear, as 
there will be quite enough moisture for the roots 
without any artificial supply. To plant, prepare a
