a kilogramme weight (over two pounds) placed 
upon the top; while a further record was 
made by a snail that moved a load of over 
three pounds, the experimenter stating that 
this was accomplished after only four days’ 
training. 
In case any of my readers may feel inclined 
to set up a stable of these mettlesome steeds, 
a few words of advice in regard to the manner 
of harnessing them may be of service, the result 
of the experiments depending a great deal upon 
how this is carried out. Narrow tape or, better 
still, strong thread should be used for the traces, 
one end being fastened to the carriage, while 
the other should be attached to another short 
thread, the two extremities of which are fixed 
on either side of the creature’s shell by means

pull, and thus avoid being lifted upwards during 
its progress.

a “ four-in-hand,” it may be pointed out that 
some difficulty may arise from the fact that 
the steeds cannot be guaranteed to step out 
together or to pull evenly. But this drawback 
may be overcome by fixing a short length of
