Half of this "book" is dry recitation of facts:
("Towards the east, outlying ranges, such as those of the Sierras de Filabrés and of Gador, attain heights of 6000 and 7000 feet respectively; while in the westward prolongations, the Mesa de Ronda is only 5000; and the chain gradually drops till it reaches the sea at Cape Trafalgar, and the rock of Gibraltar, 1400 feet.").
The other half is racist, offensive descriptions of Spaniards:
("The Galicians and Asturians...reap the harvests for the more lazy Castilians ...it is they who do nearly all the hard work in all the chief towns, not of Spain only, but also of Portugal. They are proverbially honest and trustworthy as servants, though slow and somewhat lacking in intelligence."
"The Andalusian is almost oriental in character, he is fond of song and dance and colour, yet lazy withal, and disliking sustained labour. He delights to deck himself with finery, and his women with flowers..."
"Spaniards are commonly said to be cruel and bloodthirsty, with little regard for the sufferings of others or respect for human life; and undoubtedly there is some truth in this charge, but it does not apply to the whole Peninsula.")
Only bother if you want to be bored and/or offended.
