W. E. COOKE, M.A., F.R A.S. : 
(7) Arrangements are made whereby every tele- 
phone subscriber may at any moment obtain 
true time from the Exchange free of cost. 
The error of drop of the Fremantle time ball is auto- 
matically recorded at the Observatory, and rarely exceeds- 
0.2 of a second. Amongst the minor instruments is a Milne 
seismograph, which records severe earthquakes in any portion 
of the world, and many local ones (i.e., within 1000 miles or 
so) of small intensity. 
“ Visitors’ evenings ” have always been a popular 
feature — to such an extent that it has been found necessary 
to purchase a new instrument to meet the demand. A fine 
i2|-inch reflector, by Calver, mounted cquatorially, with 
clockwork, has recently been erected near the main entrance, 
and a series of regular bi-weekly receptions instituted (with 
many others in addition). The telescope-house can be 
moved away on rails, leaving the instrument freely exposed 
in an open enclosure, with a high close fence for a wind- 
shelter. A lantern, screen, and specially selected set of 
slides, field and opera glasses, are also available, and it is 
endeavoured to make these evening receptions not only 
interesting but also educational. If the Government con- 
sent, it is proposed to extend this feature by occasionally 
taking the telescope to the Goldfields and giving lectures at 
various country towns.
