And now we come to the practical question of how we are to get it, and how to keep it.  There are several companies who undertake to deliver a daily supply of ice in town and country at a very moderate price, about sixpence a block of 10 lbs.; but when there is a larger demand for it, it will very soon be supplied at even a cheaper rate.  There is a very simple little American invention which makes ice very quickly.  It is not by any means expensive, about 21. 2s. 0d., and is invaluable in country districts away from the railway.  Then for a refrigerator there are several very simple chests which require only a small quantity of ice to keep them charged.  The smallest and cheapest is the Baldwin, costing from 30s., and another is the Iceberg, which acts splendidly.  Unlike other machines, which are liable from their complicated structure to get out of order, these are so simple that they require no repairs, but only strict cleanliness to keep them in good order.  They should be well washed out with soap and soda at least once a week, and care taken that no little bits of food are left in when the plate containing the main part is removed, for these morsels will cause an unpleasant smell and quickly taint anything that may be put in afterwards.  It is better not to break the ice up, but to put the whole block in the refrigerator, and when once it is in to close the lid securely and keep it closed.  It is a good plan to put a piece of newspaper over the block, as that forces the cold air down into the lower chamber.  The larger blocks will be found almost as cheap as the small ones, as if carefully used they last much longer.  No doubt, as the desire for ice increases, smaller blocks, costing perhaps 2d., or 3d., will be made, or the present prices reduced to that figure.  This, to a great extent, is in the hands of the consumers, for as soon as there is a more spirited demand some energetic firm will arise and supply the want, and we shall have, not only cheaper ice, but cheaper ice-chests too.  Dr. Muskett has pointed out some of the advantages of ice in his work on the health and diet of children in Australia, as will be seen from the following paragraph:—­

“In our semi-tropical climate a dislike is often taken to butter, when it is presented at breakfast in the form of semi-liquid grease.  It would require a person with the stomach of an ostrich to digest, to say nothing of relish, such an oleaginous composition during our summer months.  But if this necessary and all-important article of diet can be presented in an appetising form, what a desirable result is achieved!  The mass of the people—­I am not referring to those who are well endowed with wordly gifts—­are apt to look upon the Ice Chest as a luxury which is altogether beyond their means.  But I am firmly persuaded that if the price of ice were brought down to one halfpenny per pound, and that if a company were formed to deliver such a small quantity as six
