Chap. IX. ‘ Orange gardens—purchase of fruit—Imports 
~—Gathering and packing the fruit—varieties of lemons and. 
oranges—Grapes—V intage.”’ “ The orange and lemon. 
trees blossom in the. months of February and March.”—~ 
“‘ The trees generally attain the heighth of fifteen or twenty» 
feet ; they are planted with little regularity and are permits: 
ted to grow with unrestrained luxuriance.”—“, The usual: 
produce of a good tree, incommon years, is from sixtoeight 
thousand oranges and lemons. A few years since, twenty- 
six thousand oranges were obtained from one tree and tweuty> — 
nine thousand have been gathered from another. » ‘These 
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 acucumber 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 hang 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. 23 
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 
peculiarly interesting to the geologist, as they exhibit to 
him 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 iso!'ated 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. ‘‘ followed Daubuis- » 
son,” anda better authority it would be difficult-to find. . 
The structure of the rocks is minutely described... They 
abound. in. Olivine and Augite, and sometimes contain 
Haiiyne, basaltic hornblende, ‘Titanite, Felspar, &c. Much 
of the lava is cavernous, an expressive term which has been 
adopted from Sir George Mackenzie’s work ,on Iceland. 
ah yolioning is an accouut of one of the caverns in the 
island. ;
