_Respectfully State_--That owing to the inadequacy of the means to make the requisite investigations, your committee has not been able since the last session of the Convention to acquire much information of any farther general facts. The following notice of the cultivation of sugar in Mexico, to which your committee then briefly advertised has been obtained through the medium of the London Anti-Slavery Monthly Reporter for August, 1829. It is an extract of a letter from Mr. Ward, Mexican Envoy of the British Government to the Right Honourable George Canning, viz. _Mexico, March 13, 1826._ "SIR,--The possibility of introducing a system of free labour into the West India Islands having been so much discussed in England, I conceived that it might not be uninteresting to His Majesty's Government to receive some details respecting the result of the experiment in this country, where it certainly has had a fair trial. "I accordingly took advantage of Mr. Morier's prolonged stay here to visit the Valley of Cuernavaca, and Cuantla Amilpas, which supplies a great part of the federation with sugar and coffee, although not a single slave is at present employed in their cultivation. "I have the honour to inclose a sketch of the observations which I was enabled to make upon this journey, together with such details as I have thought best calculated to show both the scale upon which these estates are worked, and the complete success with which the abolition of the slavery has, in this instance been attended. "The valley which extends almost uninterruptedly from Cuernavaca to Cuantla Amilpas and Juncar (covering a space of about forty miles,) is situated on the road to Acapulco, at the foot of the first range of mountains by which the descent from the Table Land towards the south-west commences, about fifty miles from the Capital. "It is about 2,000 feet lower than the Table Land of Mexico. The difference of temperature is proportionably great, so that two days are sufficient to transport the traveller into the very midst of Tierra Caliente. "It is believed that the sugar-cane was first planted there about one hundred years ago; from that time the number of sugar-estates has gone on increasing, until there is now hardly an acre of ground on the whole plain which is not turned to account. "The cultivation was originally carried on entirely by slaves, who were purchased at Vera Cruz, at from 300 to 400 dollars each. "It was found, however, that this system was attended with considerable inconvenience, it being impossible to secure a sufficient supply of slaves during a war. The losses likewise, at all times, were great, as many of the slaves were unable to support the fatigue and changes of temperature, to which they were exposed on the journey from Vera Cruz to Curnavaca, and perished, either on the road, or soon after their arrival.
