sometimes gets from the cotton-bug are removable by soap and water. 

 The perennial yield, and the great quantity of cotton contained in each 

 pod, 50 grains or more, so that it takes only about 130 pods to produce 

 a pound of cotton, will always make it a desirable plant to cultivate.* 



2. Algodon de lea (lea Cotton). — So called from having been brought 

 from the valley of Tea (lat. 13^° S.), where it is grown on the farms of 

 Don Diego Elias and others. 



Descr. — Habit, of the Piura cotton. Leaves 8 x 9 - 2 in. (and even 

 broader), very deeply 3-5-cleft, sometimes down to £; lobes ovato-lanceo- 

 late, with a long distinctly acuminate point. Involucral leaves large> 

 overtopping both flower and pod, laciniate all round the margin ; gland 

 obsolete. Pod ovato-oval subacuminate, rather longer than in the Piura 

 cotton, 3- (rarely 4-) celled. Seeds 10, 11, or even 12 in a cell, partially 

 beset ivitJi short fuzz, which is greenish towards the apex, white at the 

 base, very rarely naked. Cotton scarcely distinguishable from that of 

 the Piura. 



The contents of a 3-celled capsule weighed 125 grs. ; viz., 31 seeds, 65 

 grs. ; cotton 60 grs., or 48 per cent, of gross weight. 



Obs. — This produces the largest pods, with the most numerous seeds, 

 and consequently the greatest quantity of cotton in each cell, of all the 

 kinds of cotton cultivated in Peru. As an average pod yields 60 grains 

 of clean cotton, it would take not quite 120 such to give a pound weight 

 of it. 



3. Algodon de Egypto (Egyptian Cotton). — But by no means the sort 

 usually cultivated in Egypt, which has smooth seeds, while this has 

 them clad with fuzz. It is so-called on the Chira, because raised from 

 seeds sent to Mr. Garland by the Manchester Cotton Supply Association, 

 and purporting to be from Egypt. It appears to me a sort of short- 

 stapled Georgia. 



Descr. — Of humbler growth than the preceding, and more pyramidal. 

 Ramuli and petioles subpilose, often purplish. Leaves 35 4 - 4 inches, 

 when 3-lobed (as they mostly are), 3 - 5 x 4 - 8 inches, when 5-lobed, cloven 

 only to about the middle, nearly flat, firmish, dull green, with grey pubes- 

 cence on the veins above on the entire surface beneath ; lobes ovate sub- 

 abruptly acuminate. Involucral leaves 1-8 x 1 -3 inches, greyish-green 

 or purplish, laciniated almost all round, hairy on margin and veins ; gland 

 obsolete, or at least small and colourless. Calyx with five rather large 

 triangular acute lobes, and acute sinuses. Petcds exceeding the involucre, 

 of a pale sulphur colour (almost white) in the morning, changing to a beauti- 

 ful rose towards evening. Pod 3-5-celled, oval (scarcely at all ovate), when 

 3-celled about 2 - 2 xT5 inches. 4-celled 1-9 x 1-5 inches, 5-celled 1*9 x 

 l - 6 inches. Seeds, 8 or 9 in each cell, densely clad with white or greyish 

 fuzz. 



* Mr. Stirling grows at Amotape a kind of cotton, of which the seeds were 

 procured from the valley of Zama, in South Peru. It is scarcely distinguishable 

 from the Piura, and yields at least an equally good cotton.
