summer pastures. Its use as a silage material is limited by the fact 
that it is easily made into hay and fed as such with very little waste, and 
also because corn and sorghum both out-yield if and are generally 
available throughout the region where Sudan grass is grown. 
In the semi-arid districts the highest yields are obtained when the 
grass is sown in rows, so as to allow of cultivation. The advantage in 
yield of the row over the drilled seedlings is so small, however, that 
most farmers prefer to avoid the necessity of cultivation by drilling or 
broadeasting the seed. A common grain drill handles well-cleaned 
Sudan grass seed without trouble, and the hay from drilled seedings 
is finer stemmed and matures more evenly than row plantings. 
The feeding value of Sudan grass is equal to timothy hay. In 
localities where soy beans. or cowpeas do well these legumes may be 
grown in mixtures with the Sudan grass. Such a mixture produces 4 
hay of higher feeding value than the grass alone because of the high 
protein content of the legumes. 
Sudan grass hybridizes freely with the sorghums. It is necessary, 
therefore, if pure seed is produced, to have the Sudan grass field at 
some distance from any sorghums, otherwise it will result in a mongrel —

PRACTICAL FUEL ECONOMY. 
The Federation of British Industries has decided to -start a fuel 
economy scheme, under the direction of an Expert Committee, consist- 
ing of technical representatives of firms belonging to the Federation, 
who have specialized in the question of efficient and economical fuel 
practice in various branches of industry. The committee is composed 
as follows:—Professor Bone, D.Se., F.R.S., Ph.D. (Chairman); Mx, A. 
W. A. Chivers (British Electrical Federation), Mr. F. G. Fryer 
(Messrs. Rowntree and Company Limited), Sir Robert Hadfield, Bart, 
F.R.S. (Messrs: Hadfields Limited), Mr. Henley L. Howard (General 
Electric Company, Limited), Mr. E. W. L. Nicol (National Gas 
Council), Mr. H- Stafford Rayner (Messrs. Sir W. G. Armstrong, Whit- 
worth and Company Limited), Mr. H. James Yates (Messrs. John 
Wright and Eagle Range Limited), Mr. Holbrook Gaskell (United 
Alkali Company Limited). The personnel of the committee is a suf- 
ficient guarantee that the activities of the organization will be conducted 
upon most scientific and practical lines. 
The work of the committee will be confined in the first instance to 
gas producing and steam raising plant. Its activities will probably fall 
into two main divisions: first, the assistance of individual firms, and 
second, the assistance of organized trades. The committee is collecting 
a large amount of information, which has never before been brought 
together, in regard to the fuel requirements of the great industrial 
centres and of the different industries of the country. Moreover, the 
very intimate relationship, which the Federation has established with | ~ 
the Government departments and other representative bodies concerned, 
will enable it to protect manufacturers’ interest in regard to supply in 
a way which has never hitherto been possible. It may also be neces- 
sary for the committee to take into consideration on behalf of the mem- . 
bers of the Federation such national subjects as coal conservation,
