It is nothing new
for horses to be harnessed to hemispheres
it has happened at intervals 
since the famous first experiment
when we know how to do a thing
we do it again

 

night or day the horses
are hitched up in teams
hemispheres are brought together
half to half
all the air is drawn out from between them
the seal is as wax
at a command the teams begin to haul
raising the vibrating chains
and the sphere
