VENTILATED GOODS. 199 



VENTILATED GOODS. 



The unique appearance of these goods may make them 

 objectionable at first, as wearing apparel, and yet they are 

 not more novel in that respect than many articles that be- 

 come fashionable. When applied to horse blankets, tents, &c., 

 there can be no objection of this sort. These goods are made 

 of barred or corded vellum. The articles are perforated im- 

 mediately underneath the bars or cords in different parts, 

 according to the construction or use of the article ; a leaf or fly 

 is cemented upon the bar or cord over the openings. The leaf 

 or fly is a little raised by the bar or cord above the openings, 

 so that perspiration can escape, while rain or wet is prevented 

 from entering. The leaf or fly should in general be a little 

 fulled on the upper edge, and tacked or cemented on the lower 

 edge. For further description see diagrams. Vol. II., page 

 Another kind of ventilated goods, such as pillows, cushions, life- 

 preservers, &c., are ventilated by being perforated, as represented 

 in the drawings of those articles, Vol. I., page
