laid in sheets over a mold. It is largely used for sugar molds. A 

 pail is said to outlast one made of galvanized iron, and to withstand 

 an intense degree of heat. It is not affected by acids or other cor- 

 rosive substances, and for use on ship-board is in request. The 

 price is $1.50 each, at wholesale, which some members thought 

 would prevent their coming into general use, while others said this 

 should be no objection, because it would be counterbalanced by 

 durability. The material has also been used for sugar molds with 

 great success.

claek's window sash lock. 

 Clark & Co., Buffalo, N. Y., exhibited this unique window sash 

 lock, which holds the sash at any desired point in the frame, with- 

 out window weights or springs. It consists of a small metallic 

 frame, having two small levers attached to it, with a roller in the 

 end of each lever. One roller prevents the sash from descending, 

 and the other prevents it from being shoved upward. The cheap- 

 ness and efficiency of the device for the purpose intended, seemed 

 to entitle this sash lock to great favor among the members of the 

 Club. Adjourned.
