The effect of sanitary care in the mines of Camborne is, so far as it has been carried, marked in the following table, made up by Mr. Blee, a medical practitioner in the neighbourhood, from the mortuary registers, showing the average age of death of the population as compared with the average of death in two other adjacent parishes of Illogan and Gwennap, in both of which some beneficent alterations have been made, especially in Illogan, but the works are stated to be new, and the circumstances not so favourable as at Camborne:— TABLE showing the average Ages of Persons dying above 30, and registered, in three years in the Parish of Camborne, in two years in Gwennap, and in one year in Illogan. ┌────────┬───────────────┬────────┬───────────────────────────────────┐ │ │ Males. │Females.│ Proportion per cent. of Miners’ │ │ │ │ │ Deaths by Mine Accidents. │ ├────────┼───────┬───────┼────────┼───────────────────────────────────┤ │ │Miners.│ Not │ │ │ │ │ │Miners.│ │ │ ├────────┼───────┼───────┼────────┼───────────────────────────────────┤ │Gwennap │ 45│ 60│ 64│ 16│ │Illogan │ 49│ 68│ 64│ 32│ │Camborne│ 54│ 60│ 63│ 5│ └────────┴───────┴───────┴────────┴───────────────────────────────────┘ The improvement in Camborne had not reached the residences, where the miners kept pigs, in sties close behind the house, and a dungheap is carefully fostered in a catch-pit adjacent. Dr. Barham, and the medical men practising in the vicinity, attribute to the decomposition of vegetable matter in the “soaked soil from the receptacles near the dwellings a form of fever which has been hanging about Camborne, and has often passed into the typhoid condition, and has been attended with great prostration of strength.”[30] I have obtained through Mr. Baker, of Leeds, who, as superintendent of factories, has had good means of making an accurate comparison, the following contrast of the results as shown in the state of mortality amidst the population of two contiguous manufacturing districts employed in similar proportions in the same description of work, and differing only in the state of the atmosphere in which they lived. The districts are the townships of Great Bradford and Horton, in Yorkshire, both in the parish of Bradford, and contiguous, differing only in elevation and atmospheric influence.
