industrial occupations of the kind. The metalliferous mines, such as the tin and copper mines of Cornwall, and lead mines of Derbyshire, are in pretty much the same pestiferous condition, but in one particular they are still more destructive of life than coal mines. In the latter the tired workman is lifted from the depths of the mines to the surface by a rope. The Cornwall miner, on the other hand, has to carry his exhausted body in some cases thousands of feet up a series of steep ladders to the mouth of the mine. It has been estimated that many miners have thus to make an exertion every night equal to climbing to the summit of Cader Idris, and this in an up-cast shaft used for the extraction of the foul air! The disastrous effect upon the already weary miner has long been known, yet in only a few of the great mines of Cornwall has the tireless arm of the steam-engine been called in to save him from this unnecessary labour. The machinery used is called a manmachine, and differs entirely from that employed in coal-pits. In place of a rope, a beam of wood or iron descends through the whole length of the shaft; this beam, at regular intervals of ten feet, has little platforms attached to it, sufficient to afford standing-room to a miner; at the sides of the shaft are similar platforms, at the same intervals. At every stroke of the engine the beam ascends or descends through the space of ten feet, consequently the miner has only to step from the fixed platform to the moving one to be lifted ten feet every time it ascends. In this manner as many as a hundred men are lifted at the same time several thousand feet in a few minutes, without any more exertion than is necessary to make a few score steps. This curious invention has materially benefited the miner, and where it is used there is a manifest absence of the heart disease, induced by the climbing of interminable ladders placed in an almost vertical position.

Dr. Greenhow, in his report on the prevalence of certain diseases in different districts of England and Wales, very clearly proves the deleterious nature of the lead miners' employment by the comparisons he makes between the death rates of the men and women of Reeth and Alston, which are purely lead-mining districts. In the former, the lead miners die at the rate of 2037 per 100,000 of all ages, whilst their wives, sisters, and daughters, who are variously employed, die at the reduced rate of 1711 per 100,000; in other words, lead mining in this one typical district caused an excess of no less than 326 deaths in every 100,000 inhabitants; and if we make a comparison relative to the prevalence of pulmonary disease between the two sexes above the age of twenty, we find the death-rate of the

Thus, in Redruth, in which this kind of labour is exclusively carried on, we find that in every 100,000 of population, 220 males die from pulmonary disease more than females; and in Penzance, which is exclusively a tin-mining district, the superior waste of male over female life, in the same population, of all ages, is 104.

The mason, like the miner, is particularly liable to suffer from the presence of irritating substances in the lungs. It has been asserted that in Edinburgh members of the craft rarely live more than fifty years. This is doubtless owing to the nature of the material they work upon. There is great reason to suppose that the degree of damage done to the delicate air-cells of the lung is to be measured by the nature of the particles inhaled. Thus, the ragged portions of granite detached by the chisel are much more likely to do harm than the less irregular dust of the bricklayer. In this manner we can account for the high rate of mortality said to exist among the masons of our northern metropolis. The Scourers in the potteries exercise their fearful trade in an atmosphere loaded with pulverised flints, a mineral dust of the most distressing character: we are not surprised, therefore, to hear that in this process pulmonary disease is still more rampant than among the Edinburgh masons, and is little inferior to that of the dry grinders of Sheffield, who receive into their lungs jagged particles of steel as well as grindstone dust.* It will be unnecessary to consider all the trades which

* A just appreciation of the value of life is, perhaps, of more importance to Friendly Societies than to Insurance Offices, inasmuch as the range of sickness in the working classes is much more extensive than in the upper and middle walks of life. Mr. Hardwick, in his manual on enrolled Friendly Societies, has pointed out the fact that the vast majority of these societies are based upon calculations which must in the end terminate in their bankruptcy; and among the causes which tend to this disastrous result he mentions the total disregard evinced in these clubs to a proper estimate of the states of health in. different occupations and localities. It must be clear that the potter, whose average amount of illness between the ages of 20 and 70 is more than 333 weeks, obtains a very unfair advantage over clerks or schoolmasters who may happen to be in the same club with him, and whose average of sickness during the same period is only 48 weeks. The dyer, again, who, under the present system of management of Friendly Societies, may be admitted to a club on the same terms as a wheelwright, claims for 293 weeks of sickness against the wheelwright's 64. The healthy country artisan is thus made to pay for the unhealthy town mechanic. If we take the case, again, of the miner

are affected by dust, inasmuch as the artisans employed in them are similarly subjected to pulmonary affections, if not in a like degree. Thus millers are rendered consumptive and asthmatic by the floating meal of their mills; snuff-makers by the snuff which pervades the air of their places of work; pearl buttonmakers suffer still more from the same cause; and the men of Sheffield who haft knives with cocoa-wood or ebony are affected with a disease exactly like the hay-asthma. The shoddygrinders of the West Riding, who grind and break up rags in a machine called a devil,' are subjected to what they term the shoddy fever, in consequence of the devil's dust given off in the tearing process. The dressers and preparers of hair, especially of foreign hair, are speedily broken in health by the dust and stench produced by their operations.

The evil effects arising from the prosecution of these trades sink into insignificance, however, when compared with the destruction caused by the floating fluff of flax-mills. These mills employ children of tender years, who have to work in an atmosphere loaded with vegetable particles to such a degree, that in a measure it clouds the vision. The hecklers are the chief sufferers in this department of industry, especially the children, who are, many of them, forced to work the same time as adults, that is, as long as human nature can possibly hold out. We shall have more to say, however, when we come to consider the effects of bleaching and dyeing works, respecting those trades which exhaust the youthful powers of large portions of the working population, and thus do infinitely more damage to the race than the more curious diseases of smaller trades, which may be severe enough, but do not affect more than infinitesimal portions of the population.

It would be supposed that workers on decomposing vegetable and animal matter would suffer a sickness and mortality only inferior to the artisans subjected to the emanations of poisonous metals. A priori, we should say for instance, that dustmen, nightmen, and the workers in sewers, would be amongst the most unhealthy of the working classes, and, indeed, routine sanitarians would summarily tell us that such must be the case. The begrimed and dusty scavenger, whose very name is a reproach, spends the

or the Sheffield grinder, and huddle him, without inquiry, into the same Friendly Society as the agricultural labourer, it must be clear that the latter must pay for the more than average sickness of his fellows. Until the relative value of life and of sickness among the working classes is thoroughly understood and acted upon, as regards the payments of members, it is clear that the healthy trades must be sacrificed to the unhealthy ones.

best part of his life in clearing away the disgusting refuse of civilisation; he has yet another duty to perform which brings him into still closer contact with unsavoury emanations. The lay-stall, or scavengers' yard, is of course a huge collection of the sweepings of the streets, the refuse of the markets, and the night-soil and dust of the houses, but it is not allowed to remain in a fermenting and indiscriminate mass. Almost as soon as it is deposited, men, women, and boys are employed to sift and sort the heap; bones, glass, woollen and linen rags, old iron, and other metals, have to be eliminated from the mass and set aside, and the coals and great cinders are extracted from the useless ashes by the hill-men.' It would scarcely be possible to bring human life into closer contact with filth of every kind than we find it to be in the workers in these lay-stalls. Yet, strange to say, Dr. Guy, who has investigated their sanitary condition, finds them to be among the healthiest of our working population. They are, with a very few exceptions,' he tells us, a healthy-looking ruddy-complexioned race;' that is, they wear their natural rouge under their artificial tint, reversing the more fashionable method of May Fair.

'One or two boys,' he tells us, whom I saw at work, would have been excellent models for the artist.' Our London readers will perhaps remember to have seen troops of robust and rosy-looking young women, not perhaps in afternoon toilet, making their way about five o'clock, from the Marble Arch

across Hyde Park- these are the hill-women,' chiefly Irish, trooping home to the rookeries of Westminster their appearance quite confirms Dr. Guy's views as to the healthful appearance of these workers. The master scavengers, who live with all their families amid these heaps of dusty desolation, excite the admiration of this searcher after truth still more; and at last, breaking out of the calm unimpassioned manner which the philosophical statist, who deals only with general truths, is wont to impose upon himself, he thus fairly gives vent to his admiration for the genus dustman :

To conclude this account of the health of this very useful class of men, I will merely add that the score or so of master scavengers who brought together on more than one occasion by the trial already

alluded to (an indictment for nuisance against a lay-stall keeper), as the origin of these inquiries, are the healthiest set of men I have ever I do not think, whether in town or country, such a body of men could be brought together, except by selection; and it is not going too far to assert of them, that if the comparison were limited to the inhabitants of London, or our large towns, no score of selected tradesmen could be found to match the same number of scavengers brought casually together.'

This is high praise, and doubtless deserved; but few people, however, would have suspected that Hygeia clasped so closely to her bosom the grimy scavenger in his filthy frock. Dr. Guy, however, gives us hard figures for his pleasant flourishes. If we compare the scavenger with other workmen placed under somewhat similar circumstances, he rises triumphant over them. Thus whilst the bricklayer's labourer, generally a very poor Irishman, it is true, suffers from fever a ratio of 35 per cent., and the brick-maker 21 per cent., the scavenger experiences only 8 per cent. of illness from the same cause. This result does seem astonishing when we remember that sanitarians sometimes attribute so much illness to the presence of a neglected dust heap; but as Dr. Guy very justly remarks, those emanations which may prove injurious when confined within a small space and our houses, like bell glasses, cover and keep in numberless impurities—become innoxious when fully exposed to the air. We suspect, however, that the power of ashes to absorb noxious emanations of all kinds, is at the bottom of the striking immunity which the scavenger exhibits from all febrile complaints. Nightmen and sewer-men, again, are brought into direct communication with the most disgusting, and as the public are led to suppose, the most poisonous animal effluvia; they stir in the very nidus of fever, yet it has been remarked by many observers that they are singularly exempt from this disease. Sir Anthony Carlisle tells us that out of fifty men employed in the sewers in his time, only three had had fever. Thakrah declares that out of eighteen examined by his assistant, only two had even slight disorders, and they informed him that appetite was increased by the effluvia; and finally Dr. Guy tells us that out of thirty-four nightmen examined by him, only one had had an attack of fever, and he only through being out of work for three weeks; he suffered, in short, from change of air, and perhaps want of food. Dr. Guy, in the little pamphlet we have already quoted from, states a most remarkable fact, illustrative of the changes of opinion, even amongst medical men, relative to the effects of snuffing sewer emanations. He says, that a gentleman who accompanied him in one of his inspections over a scavenger's yard, informed him that, he perfectly well recollects thirty years ago, when he was a lad, seeing as many as 'twelve patients directed by the faculty of that day to walk round "the shoots for the night-soil on his father's premises; and he ' appealed for confirmation of this statement to his brother, who 'said that he had seen scores of patients industriously inhaling 'this curious dose of physic.' Thakrah, who wrote his celebrated
