FLOWER-SACKS. 69 



IMPROVED PRESERVE JARS. 



Different methods have been suggested in this work for cork- 

 ing and covering preserve, pickle, and other jars ; another 

 method, invented by a crockery merchant of New York, 

 although somewhat more expensive, may be considered an im- 

 provement deserving particular notice. The covers of earthen 

 or china jars, (the jars being suitably constructed for this pur- 

 pose,) are, by a screw and bar, or cross-piece, pressed down 

 upon a shoulder or rest in the jar, which is made quite air- 

 tight by means of a ring or packing of gum-elastic between the 

 lid and shoulder of the jar. See plate , fig. . 



FLOWERPOTS AND VASES. 



Perforated caoutchouc whalebone or board, although expen- 

 sive in comparison with crockei'y or wood, is a suitable material 

 for flower-pots, on account of the free transmission of air and 

 moisture through it. Caoutchouc ivory, not perforated, may be 

 applied to flower-vases without the same objection of expensive- 

 ness, for the reason that it may be made so ornamental as to be 

 substituted for china, and because they are not liable to be 

 broken like china, while they are equally water-proof. 



FLOWER-SACKS. 



This is a convenient and useful little article for the florist, or 

 Others who wish to transport or carry flowers with moisture, 

 or roots with earth. They are made by machinery from gum- 

 elastic fabrics, after the method described, Vol. I., page , and 

 with such rapidity and cheapness that they may be afforded at 

 the reasonable rate which is required for a purpose like this.
