about a quarter of an inch thick, which is our indigo. The best 

 sort is brought from Biana, near Agra, and a coarser kind is made 

 near Amadabad. 



In the kingdom of Morocco, the province of Tafilet produces 

 indigo which grows without art or culture, and yields a more vivid 

 and lasting blue than that produced in the West Indies.

Logwood, 

 Haematoxylum campechianum. Link. 



The campechianum is the only species of the hasmatoxylum 

 hitherto discovered; it is a much smaller tree than the guaiacum, 

 and both the trunk and the branches are extremely crooked, and 

 covered with dark-coloured rough bark ; the smaller ramifications 

 are numerous, close, prickly, or beset with strong sharp spines ; 

 the leaves are pinnated, generally composed of four or five pair of 

 pinnae, of an irregular oval shape, obliquely nerved, and obtusely 

 sinuated at the top ; the flowers grow in racemi, or in close regular 

 terminal spikes, and appear in March ; the calyx divides into five 

 oblong obtuse segments, of a brownish purple colour j the petals 

 are five, patent, obtusely lance.shaped, and of a reddish yellow 

 colour; the stamina are somewhat hairy, tapering, of unequal 

 length, shorter than the corolla, and the antherae are small and 

 oval ; the style is nearly the length of the stamina, and the germen 

 becomes a long double valved pod, which contains many oblong 

 compressed, or somewhat kidney. shaped, seeds. 



This tree is a native of South America, and grows to the highest 

 perfection at Campeachy, in the Bay of Honduras, whence the seeds 

 were brought to Jamaica, in 1715, with a view of propagating it as 

 an article of commercial export. And though it does not appear 

 to have answered this purpose so fully as could have been wished, 

 yet we are told that in some parts of the island, especially where 

 the ground is swampy, this tree, in the course of three years, will 

 rise to the height of ten feet, and by this quick and luxuriant 

 growth, soon overrun and destroy the neighbouring plants *. The 



* In some parts of Jamaica, are such quantities of it, growing wild, as to 

 incommode the land-holders extremely." Long's 1. c. 754. He also observes, 

 that it makes an excellent and beautiful fence, which, if kept properly 

 trimmed, grows so strong and thick, that nothing can break through."
