CHAPTER XXI.
From Cabul to Kohi-Baba.
July 17th.—Proceeded from Cabul to Shah Bagh; cloudy weather, occasionally a very slight shower during the last few days, depending probably on the Punjab rains. To-day, observed a small green caterpillar, climbing up a fine thread, like a spider’s web, which hung from the fly of the tent; its motions were precisely those of climbing, the thread over which it had passed was accumulated between its third pairs of legs; it did not use its mouth.
I did not ascertain whether the thread was its own production or not; if it was, it must have come out of its tail.
24th.—The fish in the Cabul river here are, a Loach, an Oreinus, and a Barbel; none of these grow to any size, as there is but little water left in the river in consequence of the drain for extensive cultivation on both the east and west sides of the city.
Small specimens of these fish, especially the Loach and Oreinus, are found in the canals or larger watercuts, in which the current is slow and regular. It is curious that in the canal near the Shah Bagh, which has been lately turned off above the Cantonment, all the specimens of the Loach left in the pools of water were dead, while the Oreinus did not appear to have suffered.
This Loach is a Cobitis propria, it has the usual form of that genus, the spots are disposed irregularly, rarely becoming banded. The shape of the head is curious, the forehead being prominent, this gives the mouth an appearance of unusual depression. [{479}]
The country both on the east and west sides of Cabul may have been formerly a lake. Such indeed would seem to have been the origin of all the valleys in which there is an expanse of tillable ground, and not mere strips confined to the banks of the draining streams.
The eastern valley is indeed partly occupied by the large sheet of water to the north, and the west is very marshy. The eastern one is interspersed with low detached ranges of hills.
The birds are a magpie, a dove, Oriolus, Pastor roseus, Pastor alter, sparrow, water-wagtail, Hirundo, Hoopoe, Lanius, Sylvia sp., water-hen, wild ducks on the lake, and Merops; almost all these as at Khujgal, but no minas, or Edolia.
