In the interior, though the lakes, being salt or brackish, had no piscatory stores, the rivers were, for the most part, it would seem, well provided; at least, good fish are still found in many of the streams, both small and large; and in some they are exceedingly plentiful. Modern travellers fail to distinguish the different kinds; but we may presume that they are not very unlike those of the adjoining Media, which appear to be trout, carp, barbel, dace, bleak, and gudgeon. The reptiles of Persia Proper are not numerous. They are chiefly tortoises, lizards, frogs, land-snakes, and water-snakes. The land-snakes are venomous, but their poison is not of a very deadly character; and persons who have been bitten by them, if properly treated, generally recover. The lizards are of various sizes, some quite small, others more than three feet long, and covered with a coarse rough skin like that of a toad. They have the character of being venomous, and even dangerous to life; but it may be doubted whether they are not, like our toads and newts, in reality perfectly harmless. The traveller in Persia suffers less from reptiles than from insects. Scorpions abound in all parts of the country, and, infesting houses, furniture, and clothes, cause perpetual annoyance. Mosquitoes swarm in certain places and seasons, preventing sleep and irritating the traveller almost beyond endurance. A poisonous spider, a sort of tarantula, is said to occur in some localities; and Chardin further mentions a kind of centipede, the bite of which, according to him, is fatal. To the sufferings which these creatures cause, must be added a constant annoyance from those more vulgar forms of insect life which detract from the delights of travel even in Europe. Persia, moreover, suffers no less than Babylonia and Media, from the ravages of locusts. Constantly, when the wind is from the south-east, there cross from the Arabian coast clouds of these destructive insects, whose numbers darken the air as they move, in flight after flight, across the desert to the spots where nature or cultivation has clothed the earth with verdure. The Deshtistan, or low country, is, of course, most exposed to their attacks, but they are far from being confined to that region. The interior, as far as Shiraz itself, suffers terribly from this scourge, which produces scarcity, or even famine, when (as often happens) it is repeated year after year. The natives at such times are reduced to feeding on the locusts themselves; a diet which they do not relish, but to which necessity compels them. The locusts of Persia Proper are said to be of two kinds. One, which is regarded as bred in the country, bears the name of _missri_, being identified with the locust of Egypt. The other, which is thought to be blown over from Arabia, and thus to cross the sea, is known as the _melelch deriai_, or “sea-locust.” The former is regarded as especially destructive to the crops, the latter to the shrubs and trees.
