the hard quality of the water; and, perhaps, as an approximative calculation, £200,000 worth of soap is annually wasted without being useful as a detergent. This enormous tax on the community results from the hardness both of the well and river water; the former being generally much harder than the latter. But this expense, large as it may seem, is not the only consequence of a bad water supply. The labor required to wash with hard water is very much greater than that necessary when it is soft, this labor being represented in the excessive charges for washing. In fact, extraordinary as it may appear, it has recently been shown in evidence before the General Board of Health, that the washerwoman's interest in the community is actually greater than that of the cotton-spinner, with all his enormous capital. An instance of this will suffice to show our meaning: a gentleman buys one dozen shirts at a cost of £4, three of these are washed every week, the charge being fourpence each, making an annual account of £2 12_s._ The set of shirts, with careful management, lasts for three years, and has cost in washing £7 16_s._ The cotton-spinner's interest in the shirts and that of the shirt-maker's combined, did not exceed £4, while the washerwoman's interest is nearly double. A considerable portion of this amount is unavoidable; but a very large part is due to the excessive charges for washing rendered necessary by the waste of soap and increased labor required for cleansing. A family in London, with an annual income of £600, spends about one-twelfth of the amount, or £50, in the expenses of the laundry. On an average, every person in London, rich and poor, spends one shilling per week, or fifty-two shillings a year for washing. Hence, at least five million two hundred thousand pounds is the annual amount expended in the metropolis alone for this purpose. Yet, large as this amount is--and it matters not whether it be represented in the labors of household washing or that of the professed laundress--it is obvious that the greatest part of it is expended in actual labor, for the washerwoman is rarely a rich or even a thriving person. Hence, it follows that this labor, barely remunerative as it is, must be made excessive from some extraneous cause; for it is found by experience that one-half the charge is ample compensation in a country district supplied with soft water. The tear and wear of clothes by the system necessary for washing in hard water, is very important in the economical consideration of the question. The difference in this respect, between hard and soft water, is very striking. It has been calculated that the extra cost to ladies in London in the one article of collars, by the unnecessary tear and wear, as compared with country districts, is not less than, but probably much exceeds, £20,000.
