a IX. “ Orange gardens—purchase of fruit—Imports 
therin g and wen ars the fruit-—varieties of lemons and 
ora anges—-Gr rapes— Vintage.” ——“ The orange and lemon 
trees basi in the months of Bokeuaty and March.”— 
“The trees generally attain the heighth of fifteen or twenty 
feet ; they are planted with little regularity and are permit- 
ted to grow with unrestrained luxuriance.”—“ The usual 
produce of a good tree, incommon years, is from six to eight 
thousand oranges and lemons. A few years since, twenty- 
six thousand oranges were obtained from one tree and twenty- 
nine thousand have been gathered from another. ese 
quantities have never been exceeded. A singular variety of 
Jemon and orange is described which has “a very irregular, 
lobulated appearance ; and different lobes of the same or- 
ange or lemon retain the distinct sweet or sour taste.” Some 
of these arc shaped “like a cucumber with numerous long 
slender processes growing out from the sides ; some have 
a form very similar to the human hand, with projections 
like fingers ; and some rede in clusters, or resemble large 
oranges or lemons to which smaller ones, of the size of bul- 
lets are attached,” &c. These are produced by innocula- 
ting the common, or sweet orange, with the sour oranges 
and lemons. 
Chap. X. Dismissing the popular topics which however 
we have found very interesting, we now advert to the 
Geological features of St. Michael, &c. “ The Azores are 
gorse interesting to the geologist, as they exhibit to 
im at every step marks of their comparatively recent for- 
mation, and of the operation of agents the most powerful 
and terrific.” The island is described, first generally, and 
presents lofty mural precipices, deep ravines, lofty moun- 
tains, and isolated conical hills with craters at the top. The 
principal variety of Lava is of the basaltic kind, in applying 
this term the author observes, he has “ fallawed Dau 
son,” and a_ better authority it would be difficult to find. 
The structure of the rocks is ~ : roan ey 
abound in Olivine and Augite, a mes contain 
Haityne, basaltic hornblende, Titanite, Fdinghes &c. Much 
of the lava is cavernous, an expressive term which has been 
[from Sir George Mackenzie’s work on Iceland. 
The ae is an accouut of one of the caverns in the
