384 Miscellanies. 



In the mean time it is proposed to instruct twenty women, who shall 

 be able to exhibit the filature in actual operation, when the young 

 men shall assemble in the following year. 



As there can be no filature without coccoons, it is proposed that 

 Mr. Homergue should travel variously in the United States to obtain 

 them, and to promote as much as possible the culture of the mul- 

 berry tree and the raising of silk worms. 



It is proposed to encourage by suitable bounties the planting of the 

 white Italian mulberry tree, as silk worms and coccoons will naturally 

 follow where this is done. 



To this important and patriotic effort we wish all possible success ; 

 and it cannot be in better hands than those of the gentlemen who 

 have undertaken to promote it in the United States. 



Dr. Pascalis has made great efforts and sacrifices on this subject. 

 Mr. Duponceau is giving the weight of his character to the same ob- 

 ject, and it is fortunate for this country that eminent natives of 

 France, so long distinguished for the manufacture of silk, are bring- 

 ing their knowledge and early partialities to bear on this subject, which 

 is evidently of the greatest national importance. 



21. Porcelain of Philadelphia. — This fine product of our domes- 

 tic arts was mentioned in Vol. XIV. pa. 198 of this Journal. There 

 is little to add to what was then (we have great pleasure in saying 

 truly) stated, relative to the beauty and excellence of the porcelain 

 of Philadelphia ; but a recent visit to the manufactory, places it in 

 our power to say, that it is going on with vigor and success. It is 

 now under the entire management of Mr. Tucker, and there is ex- 

 hibited in his premises sufficient evidence of skill, good judgment, 

 perseverance and efficiency, to justify the belief that the establish- 

 ment will be permanent, and will admit of due extension as the de- 

 mand shall increase. 



Mr. Tucker is very fortunate in the possession of the best materi- 

 als, which are obtained in the greatest abundance, in the southern 

 parts of Penn. and in Delaware. Besides the proper porcelain 

 clay, he uses also feldspar and quartz. The feldspar is from a huge 

 vein in Delaware ; the most common pieces that are used in the 

 manufactory are beautiful, and many of them sufficiently so to form 

 ornaments of cabinets, being little inferior to the adularia of the 

 Alps : white quartz is also used : both are calcined to aid the pul- 

 verization, which is effected by proper mills ; the powders are then 

 mingled in water, and form an excellent basis.
