spread over eight square yards or more. It is of 
weeping habit, yields a good oil in fair quantity, and 
resists well the attack of insects. 38. The Mouraou, 
or Mourette, a large tree, furnishing also oil of a very 
fine quality. Olive-trees require judicious pruning 
immediately after the fruit is gathered, when the sap 
is comparatively at rest. They may be multiplied 
from seeds, cuttings, layers, suckers, truncheons or 
estacas, and old stumps, the latter to be split. The 
germination of the seeds is promoted by soaking the 
nutlets in a solution of lime and wood-ash. The seed- 
lings can be budded or grafted after a few years. 
Truncheons or estacas may be from one to many feet 
long, and from one inch to many inches thick ; they 
are placed horizontally into the ground. Olive plant- 
ations at Grasse are worth from £200 to £250 per acre. 
For many details the tract on the ‘Culture of Olive 
- and its Utilization,’’ here recently issued by the Rev. 
Dr. Bleasdale, should be consulted, as it rests largely 
on its author’s observations during a long stay in Por- 
tugal. The olive-oil imported last year into Victoria 
was valued at £15,638. 
The following notes are derived from the important 
‘¢Tratado del Cultivo del Olivo en Espafia,”’ by the 
Chey. Capt. Jose de Hidalgo -Tablada (second edit., 
Madrid, 1870). The Olive-tree will resist, for a short 
time, considerable frost (— 15° C.), provided the 
thawing takes place under fogs or mild rain (or per- 
haps under a dense smoke). It requires for ripening 
its fruit about one third more annual warmth than 
the vine. The olive-zones of South Europe and North 
Africa are between the 18° and 44° N. L. An eleva- 
tion of about 550 feet corresponds, in Spain, as far as
