er wears nor holds its shape so well. Mohair is very light in weight and cool looking. As a matter of fact, however, it is a fairly good conductor of heat, is closely woven, and usually comes in dark shades. It is a woolen cloth, and any woolen has its threads woven more closely on account of the process of manufacture than linens, cotton, and silk cloths. Linen is perhaps the best material for summer wear. It is porous in weave, light in color, and of fairly light weight. It is well to remember that the safety valve of the body in hot weather is the evaporation of perspiration, not the act of perspiring. If the hand is put in a glove, for instance, it will perspire much more than if in the open air, but it will not be as cool. It is the evaporation that is a cooling process. If the perspiration is absorbed it cannot evaporate. That is why loose fitting undergarments are cooler than tight ones. It is also the reason why cotton is cooler next to the skin than linen or silk; it absorbs moisture less freely. DRINK PLENTY OF WATER.--Water, and a great deal of it, is desirable at any time during the summer. It should be drunk freely during the day. Lemonade also is good, the slight acid being an aid to digestion. It is best to have beverages cooled only to a moderate temperature. Ice water is not bad, but it would be preferable if it were not at so extreme a temperature. Ice is resorted to only as a convenient means of securing a palatable temperature; the system does not crave extreme cold. Water at the temperature of the air is nauseating, so ice is put into it and the other extreme secured. Sixty degrees is the ideal temperature for drinking water. If this could be conveniently obtained it would be preferred to a greater degree of cold. Not only is it less harmful to the system, but it is more satisfying and thirst-quenching. Water put in bottles and left in a refrigerator until properly chilled is the best way of preparing a summer beverage. When any beverage is sufficiently cold to cause a pain in the head or throat when drinking it the result may be harmful. Cold water poured on the wrist or head has a cooling effect and tends to reduce the ice water habit. If one could afford it, it would be well to drink nothing but mineral water in the summer. Not only does it assure purity, but the gas is an aid to digestion and serves to render the water more palatable. This results in more of it being drunk than if it wer
