a half in circumference, Captain Stewart, the gentleman with 
whom I was travelling, remarked that it had a striking resemblance 
to the broom, but it did not, we were informed, bear a yellow flower. 
The leaves were small and narrow, and underneath we saw the gez 
spread all over the tender branches like white uneven threads, with 
innumerable little insects creeping slowly about. 
These little creatures appeared to: derive their subsistence from 
the leaves and young bark of the bush they inhabit; and this is the 
opinion of the country people. They are either three distinct species 
of insects, or one in three different stages of existence: one kind is 
perfectly red, and so diminutive as to be scarcely perceptible ; the 
second, dark and very like a common louse, though not so large ; 
and the third, exactly like a very small fly. They are extremely 
dull and sluggish, and are found lying or creeping about between the 
bark of the gavan and the gez. The peasants, as well as the 
inhabitants of Khonsar, were decidedly of opinion that this curious 
substance is the production of these minute animals, as neither the 
insect nor the gez are found onany other tree in the neighbourhood ; 
nor can we be allowed to imagine it may be a vegetable gum, as no 
appearance of any gummy liquid oozing from fissures in the bark 
of the bush could be observed on the closest examination. The people 
who are engaged in the collection of this curious article continue 
their occupation every third day for twenty-eight days during 
September. A journey, which I subsequently made to Baghdad, con- 
vinced me that the gezis not exclusively confined to this district, but is 
found in the range of mountains running through Koordistan, 
dividing Persia from Asia Minor and Mesopotamia, where it is called 
manna by the Armenians, and said to be exported in quantities 
s aitines Erzeroom to Constantinople. (By Captain B. Frederick, 
om the “ Transactions of the Literary Society of Bombay,” Sep- 
Sale 28th, 1813.) 
—The gavan is Tamarix gallica, var. mannifera, Ehrenb., and the aphis, 
which feeds upon it and produces the gez, is the Coccus manniparus of Ehrenberg. 
name Gezangabeen is loosely applied by the Persians to the true manna 
obtained from Cotoneaster nummularia in Korasan, the correct name of which is 
Shirkhisht.
