The internal surface of the iron may be easii\ preserved by coating 

 with a thick lime wash composed of lime and skim milk, the milk being 

 used in the same way as water in ordinary whitewash. The alkaline 

 jjroperties of lime neutralize the acids jjroduced in the fermentation of 

 the green fodder and prevent its action in corroding the iron. An iron 

 .silo coated in this way will, with reasonable care, keep bright and clean 

 and will last for many .seasons. The outside should l>e protected with a 

 coating of tar. The following are some of the advantages of this type 

 of silo : — 



Durability. — When protected as above it is practically indestructible. 

 Being made entirely of iron there is no danger from white ants, fire, 

 rotting or warping of timber, &c., and it will also be vermin proof. 



Portability. — It can be moved from paddock to paddock by means of 

 horses and dray, the .sections when packed making at>out a two-horse load. 

 (Jftentimes it would be a great saving of time and labour for a farmer to 

 move his plant and silo to the crop rather than bring the crop to it. 



Future Enlargement.— The silo can be enlarged in diameter or height 

 by simply erecting more sections. 



As a storage cylinder for grain or chaff the .sdo described would be 

 ff)und verv suitable.

Treacle Mustard. 



Erysimum rcpanduin. L. {Crucijera). 



A tall erect herb; stem much l>ranched at the top; leaves narrow, lance- 

 shaped, with somewhat toothed edges ; stem and leaves bearing more or less 

 .scattered forked hairs. Flowers yellow, clustered in elongated terminal 

 racemes; stigma seated on the top of the ovary. Pods spreading, hardly 

 thicker than the short stalks ; seeds oblong, rust-colored. 



A smaller variety exists with a simple unbranched stem, about 6 inches 

 iliigh, but the ordinary form ma\ attain a height of 2 feet or more in good 

 -soil. Tn poor drv soil it may develop as an annual, though under less 

 severe conditions it usually lasts for two years, or even longer if the con- 

 ditions are very favorable and the formation of seeds not abundant. 

 Stronglv flowering and seeding plants usually exhau,st themselves and then 

 die, but the seeds are very abundant, and some mav remain living in the 

 soil at least three years, and possibly longer. 



On permanent pastures, cutting and the fjrevention of flowering and 

 seeding will keep the plant under. In cultivated ground a bare fallow 

 or a crop of potatoes will help to clean the ground, if the .seedlings are 

 killed as they appear, and given no chance to establish themselves. Care 

 should ha taken that no seed is sown which contains the seeds of this plant. 

 They can Ije recognised bv their oblong shape and reddish color, and an- 

 .(bout the size of ordinary mustard seed. 



This plant has l>een wrongl\ called " Wild Mustard." whirh name ap- 

 plies to the " Charlock," Brassica sinapistrum, Boiss. 



It is a native of Southern Europe. 



Proclaimed for the Shire of Wimmera, December, 1900.
