sionally on newly broken ground where no crop has ever yet been grown. 
This would seem to indicate that certain soils harbor the organism as a 
saprophyte. Poorly drained ground often shows the same tendency. 
The soils otherwise best adapted for cabbage growing are those on which 
the organism can survive best, e. r/., bogs and swamps which are rendered 
arable, but crops grown on sandy loam are less subject to the disease, 
as are also those grown on calcareous soils. Wherever a limestone for* 
mation outcrops both cabbages and turnips are comparatively free from 
attack. Some of the Long Island gardeners raise cabbages season 
after season on the old shell heaps without any trace of the disease. 
It often occurs that turnips or cabbages grown on ground previously 
covered with compost heaps show the disease, while the plants all 
around them are free. Fertilizers should not be spread over the ground 
in the autumn, since it is known that the various kinds of manure form 
an excellent substratum for the development of certain Myxomycetes. 
If applied, it should by all means be thoroughly fermented. 
It is quite evident, from the nature of the disease, that after having 
gained access there is probably no cure. Preventives are apparently 
the only means by which the ravages of the disease may be averted. 
Probably the want of clean cultivation is one of the most fruitful sources 
by which the disease is propagated. Of all the various preventives, 
ashes, salt, chalk, lime, bisulphide of carbon, etc., suggested by both 
gardeners and scientists, lime seems to be the most effectual. If ap¬ 
plied to the land during the spring immediately preceding, it very sel¬ 
dom has any effect on the ensuing crop, but if applied a year and a half 
before, it almost invariably has a surprising effect in preventing the 
disease. It is only by extended experiments that the best methods of 
application can be determined. Since many believe the disease origin¬ 
ates largely in the hot-bed before transplanting, sterilization of the soil 
should be tried. Mixing certain proportions of unslaked lime with the 
soil used in the hotbed will undoubtedly modify, to a considerable ex¬ 
tent, the occurrence of the disease. Hulst 16 makes a saturated aqueous 
solution of chloride of lime, sold by druggists as u bleaching powder.” 
This solution is diluted with three parts water and applied to the roots 
of the plants and to the surrounding soil at the time of transplanting. 
In from two to three weeks this is followed by a second application. 
In conclusion, I wish to call attention to certain forms that are al¬ 
most constantly present. Sections of tissue containing plasmodia are 
rarely examined in which there are not present minute bodies undergo¬ 
ing vibratory movements very similar to that known as the u Brownian 
movement.” The granules are very large, and indeed so much do they 
resemble micrococci that one is led almost irresistibly to the conclusion 
that this is the explanation. If this be true it is questionable to just 
what extent we are dealing with true plasmodia. Ward 32 finds the so- 
called plasmodia described by various authors as occurring in the tuber¬ 
cles found on the roots of Vida Faba to be nothing more than the pro-
