Nore.—The following plants were all collected upon one mound 
of a peculiarly heavy and tenacious loam, which formed a part of 
the ballast of a ship trading to South America, and is believed to 
have come from the Rio dela Plata. A giant form of Chenopodium, 
which never developed flowers, and could not on that account be 
definitely named—but its nearest British representative is Cheno- 
podium album.  Ximenesia australis, Bowlesia tenera, Medicago 
denticulata, M. maculata, Bromus schraderi, Verbascum pheniceum, 
and a very pretty sevecio, with finely divided leaves, which has not 
been identified. 
DERWENT TIN PLATE WorkKS, WORKINGTON.—Quite a different 
and in many ways a remarkable condition of things is apparent 
here. Behind the works on the east side is a large accumulation 
of ashes and cinders, mixed with other rubbish, forming a raised 
embankment four or five yards in depth, and about forty or fifty 
yards in extreme length. A footpath used by the workpeople 
passes along the southern base. During the early summer of 
1889 I noticed along this track a large number of plants unknown 
to me previously. On inquiry at the works, I was informed that 
the material upon which the plants were growing consisted of 
refuse from the tin plate works. It came by sea from Liverpool, 
and, after being applied while in a heated state for imparting a 
polish to newly-made tin plates (on much the same principle as 
pins and needles are rendered bright by rapidly revolving in heated
