[ Equisetum . 
point of view, is not cultivated along our sandy coasts, where it would grow 
luxuriantly and rapidly, forming a strong embankment, and yielding a considerable 
profit. The Dutch are well acquainted with the value of its long and matted 
roots in restraining the wasting effects of the ocean, which would soon undermine 
their dykes were it not for the Equisetum hyemale which is planted upon them. 
At the proper season it is cut down and exported to other countries, where its 
naked and flinty stems are used for polishing domestic utensils, furniture, marble, 
&c. It is here sold as Dutch rush (not Dutch rushes, which are Scirpus glaucus, 
or sometimes Scirpus palustris ; the former being used for the bottoms of chairs, 
the latter by coopers to stop leakages). 
So abundant is the silex upon both the imier and outer surface of the stem, that 
the whole of its vegetable matter may be removed without destroying the 
shape of the plant. Every part of it is a very beautiful object under the 
microscope.
