4. Mr. Cowing also proposes a method of concentrating cane- 

 juice and boiling sugar, which is intended to obviate the many 

 difficulties that attend the manufacture of raw sugar in the open 

 kettles, which are still employed to so great an extent in the 

 plantations of Louisiana. There cannot be a doubt that Mr, 

 Cowing's is very superior to the ancient mode, and therefore well 

 worthy of the attention of planters. How far it might be a sub- 

 stitute for the improved method of heating by steam, or evapora- 

 ting in vacuo, your committee cannot venture to decide ; and in 

 this case, also, they trust that experiments on a suificient scale 

 may be made by those who are so deeply interested in the pro- 

 duction of sugar. 



All of which is respectfully submitted.

REPORT ON THE COTTON SEED OIL AND SOAPS MANU.FACTURED BY 

 WM. WILBUR OF NEW ORLEANS. 



That they have examined the specimens of purified oil from cot- 

 ton seed, both summer and winter strained; of coarse and fine 

 soap prepared from the same material; and the cake from which 

 the oil has been expressed, exhibited by Mr. William Wilbur, of 

 New Orleans. The oil appears to have been completely purified 

 from all the impurities which have hitherto been an obstacle to 

 the introduction of the cotton seed oil into general use. As far 

 as they are able to judge, when thus purified it may be applied to 

 all the uses in the arts for which olive di\ and other vegetable 

 oils of similar properties are adapted. It is also well suited for 

 feeding lamps, but at the present season they have not been able 

 to test the property of resisting frost in the specimen of winter-
