or leather, making at the same time a neat, untearable edge and a convenient means for attachment to the hat. From time to time various inventions have been made for the ventilation of boaters, these generally consisting of some open work straw being used at the base of the crown instead of the nearly impermeable rustic. This, when covered with a thin band of ribbon, is not visible from the outside, and affords some fair degree of air passage. Other methods have been adopted by having a punctured edge to the sweat band, which permitted air to freely circulate close to and all around the head of the wearer. To increase the resiliency of the leather or imitation leather lining, patents have been taken out for pneumatic surrounds, forming an air cushion all round the hat, which incidentally allows in the easiest manner for any discrepancies, and they are very common, in the contour of the wearer’s skull. The various devices for increased comfort and utility in boater linings are very numerous, and display great ingenuity. The “Autoform” The “Bon-Ton-Ivy” and the “Eesola” pads, each of them specialities of various makers of boater sweatbands, present differing features creating resiliency around the head of the wearer. These are produced by means of soft material insertions under the leather or other lining, or of cellular impressions made in the leather, or of a continuous roll all around the head fitting part, or even of the insertion of a pneumatic tube, all creating a cushion like addition to the flatness of the lining material. Each has its peculiar merits, and for certain purposes are perfect in their utility. Some are very little more costly than the plain leather, but others from the extra material and work involved are naturally more expensive, but the efforts of their manufacturers to raise the standards of quality and of efficient comfort are such as to deserve special commendation.
