ANNIVERSARY ADDRESS. tI 
the value of what are termed the salt bushes of this country. It is 
believed, and with good reason, that this class of plants possesses 
a medicinal property of great advantage to sheep, which not only 
relish but fatten on this food, particularly in seasons of drought. 
It has not been determined which are the most valuable of these 
plants, a list of which is herewith appended. It is generally con- 
sidered that of these Atriplew halimodes and Atriplex vesicaria 
are the best, but these are only found in certain localities—those 
called cotton bushes, Kochia aphylla and Kochia villosa and also 
Chenopodium nitrariaceum as well as others, afford excellent pas- 
turage, but this is all that is really known of these most interest- 
ing and useful plants. The same remarks which have been made 
respecting these plants may be applied to the grasses of this 
country. -Although the names and affinities of these have been 
botanically determined, we have yet very much to learn as regards 
the comparative nutritive value which these individually possess. 
An attempt has been made by Baron von Miieller to fix accurately 
the percentage of albumen, gluten, starch, gum, sugar, and fibre 
of the best of these, as compared with the best kinds of English 
grasses ; but this attempt has not been brought to a satisfactory 
conclusion, as the different kinds experimented on have not yet 
been obtained at different stages of development and from various 
soils, so that the mean of different analyses may be taken. Thisis 
a most praiseworthy effort on the part of the Baron, and it is well 
worth imitating by some of our practical chemists ; but however 
valuable the information derived in this way may be, we must look 
to the occupants or owners of our sheep and cattle runs to practi- 
cally learn the real value of these plants. Observations of this kind 
should be based upon some intelligent principle, and it should be 
carefully noticed the kind of situation, whether low or high, dry or 
damp, and the nature of the soil in which the — aT suc- 
ceed best, whether early orlate in flowering, and th 
fatten best by feeding upon them. In very many parts of the hai 
particularly on the sheep runs, a good number of the best grasses 
have been entirely destroyed by being too closely eaten down, for 
instance the well-known kangaroo grass, Anthistiria Australis,
