* Hop-hinds properly macerated in water, like hemp , will make cloth or paper. 
The part of the hop which is used as a bitter, is the leafy calyx of the female, 
which is expanded and lengthened. 
•f- Mastich (a resin) is from the pistacia lentiscus. 
♦ The large tuberous roots of the smilax China , properly prepared, afford a 
nourishing food to the Indians. 
§ The blossoms of the populus nigra (black poplar) yield by pressure an oil, or 
resin, which consolidates in the usual temperature of the atmosphere, and which, 
when made into candles, is found to give a light cheaper than that of tallow, and 
more brilliant than that of wax.—.It is a native of Britain, and flowers in April.
