PARTICULARS OF A CYCLONE IN THE NEIGHBOURHOOD 
OF CHESTER, July 21st, 1904, 
By Mr. J. A. McCMIcHAEL, B.A., B.Sc. 
I observed a whirlwind of extraordinary violence pass over the fields of the 
Bache Hall Estate, at 10-30 a.m. on the above date. The vortex at the base was 
about ten yards across; and the hay, which was lying in heaps, was caught up and 
raised in masses to a great height — probably 500 feet. As shown in the map, the 
whirling was ‘contra clockwise,’’ and the whole disturbance passed across the fields 
in a similar circular direction. There was a dead calm over the rest of the estate, 
and the path could be easily traced by noticing how some of the trees were in 
violent motion, while others quite close to them were perfectly motionless. The 
morning was very hot, but in the track of the cyclone (which I purposely entered) 
the wind was icy cold. About six heaps of hay were bodily removed, and some 
of it was deposited in the Asylum grounds—nearly half-a-mile away.
