"A population officially put at 50,000 should in ten years have grown by natural increase to certainly 52,000 or 53,000 souls, seeing that every Indian marries--a bachelor or spinster Indian is unknown--and that respect for marriage is ingrained in uncivilised Indian nature and love of children, probably the strongest affection these people display. By computations made last year and the year before, by officials and by those interested in the prosperity of the Peruvian Amazon Company, the existing population of the entire region is now put at from 7,000 Indians, the lowest calculation, to 10,000, the highest. Around some of the sections or rubber centres whence this drain of rubber has been forced, the human sacrifices attained such proportions that human bones, the remains of lost tribes of Indians, are so scattered through the forests that, as one informant stated, these spots 'resemble battlefields.' A Peruvian officer, who had been through the Putumayo since the date of my visit in 1910, said that the neighbourhood of one particular section he had visited recalled to him the battlefield of Miraflores--the bloodiest battle of the Chilean War. Moreover, these unarmed and defenceless people, termed, indeed, in the language of prospectuses, the 'labourers' of this particular company, were killed for no crime or offence, and were murdered by the men who drew the highest profits from that company. They comprised women and children--very often babies in arms--as well as men and boys. Neither age nor sex was spared; all had to work rubber, to perform impossible tasks, to abandon home and cultivation of their forest clearings, and to search week by week and month by month for the juice of rubber-yielding trees, until death came as sudden penalty for failing strength and non-compliance, or more gently overtook them by the way in the form of starvation or disease. With all that it has given to the Amazon Valley of prosperity, of flourishing steamship communications, of port works, of growing towns and centres of civilisation, with electric light and tramways, of well-kept hospitals and drainage schemes, it may well be asked whether the rubber-tree has not, perhaps, taken more away. "However this be, it is certainly in the best interests of commercial civilisation itself, and of the vital needs of the trading communities upon the Amazon River, that the system of ruthless and destructive human exploitation which has been permitted to grow up on the Putumayo should be sternly repressed. Peru herself can only greatly benefit from the establishment of a civilised and humane administration--a task of no great magnitude--in those regions hitherto abandoned to the _cauchero_ and the vegetable filibuster. The healthy development of the Amazon rubber industry, one of the foremost of Brazilian needs, calls for that humanity of intercourse civilisation seeks to spread by commerce, not for its degradation by the most cruel forms of slavery and greed.
