removing the sheep from water as soon as their thirst is 
satisfied, and keeping them during the heat of the day in 
shady and breezy spots. 
On the Clarence, many cattle were found to have suffered 
from eating the Moreton Bay chesnut. 
The Cumberland disease has been observed by Mr. Busby, 
of Cassilis, to increase and decrease with corresponding 
changes of temperature. Mr. Meston intimates that the bad 
food cattle eat, in consequence of the overspreading of the 
pasturage by weeds, irritates the mucous membrane, and 
thereby predisposes the system to the inflammatory influences 
of hot weather. The denudation of the primitive pastures, 
unaccompanied by any attempt to supply fresh grasses, has, 
he considers, injured the healthiness of the herbage on many 
of the older runs. Mr- Moore, who accompanied Mr. 
Meston in his trip, gives a botanical appendix, in which he 
quite confirms the statement that a great change for the 
worse is visible in the pasturage of the settled districts, and 
that the evil is spreading with alarming rapidity. 
Mr. Meston also intimates that ignorance in the manage¬ 
ment of stock has a great deal to do with the weakly consti¬ 
tution of many animals, and that the mysteries of breeding 
are but dimly understood by many of those who undertake to 
superintend stations. He has the audacity to say that the 
management of stock is an art only to be acquired by long 
practice, and that it is not altogether wonderful if, in a 
country where capitalists invest in pastoral pursuits almost 
as readily as they buy bank shares, many fatal blunders 
should be made. As a cure for such ignorance, he hints at 
the expediency of a professorship of agricultural and pastoral 
pursuits. 
The sum and substance of Mr. Meston's report, therefore, 
virtually is to the effect that there are three principal causes 
of disease in stock—overfeeding after continued starvation— 
bad diet—and unskilful superintendence .—Sydney Morning

THE ENTERIC JUICE- 
The following are results arrived at after numerous ex¬ 
periments by Professor Busch, of Bonn : 1. Hunger is con¬ 
stituted by two sensations; the first is represented by the 
nervous system in general, and derived from the impoverished 
condition of the tissues; the second originates with the 
nerves of the digestive organs, indicating their emptiness. 
The former is removed only by the required assimilation of
