The present yield of limes from the whole of the Experiment 
Station is approximately 2,000 barrels per annum. As the 
newly planted land comes into bearing this figure should rise to 
between 3,000 and 4,000 barrels per annum, and later on with 
all the trees in full bearing between 6,000 and 7,000 barrels may 
be expected. 
Some time in the near future it may be possible to deal with 
these limes in the factory which is now in course of construction 
in the Experiment Station. Such a factory will become an 
essential part of the experiments in connection with the lime 
industry, and may be expected to help the planter to solve a 
few of the difficulties that still remain to be overcome in regard 
to the manufacture of lime products. 
Experimental work in the factory conducted in conjunction 
with field operations might bring to light a better means of 
working and improving the present lime industry, and show a 
more economical and profitable method of dealing with the 
lime from the time the tree leaves the nursery bed until its 
products are ready for the market. 
VII.—_KIKUYU GRASS. 
(Pennisetum clandestinum, Chiov.) 
O. STAPF. 
In 1911 Mr. J. Burtt-Davy received from Mr. David Forbes 
of Athole, Amsterdam, Transvaal, a single root of a peculiar 
grass which he had collected on the shores of Lake- -Naivasha, 
Kikuyu, whilst hunting there, the grass having attracted his 
attention by the partiality which the wild game showed for it. 
The root was transplanted in one of the plots of the Botanical 
Station at Groenkloof, Pretoria, and soon established itself.* 
It has since flowered there regularly every year, but not seeded, 
the original plant and its descendants being apparently all 
functionally female.t In ‘‘ The Farmer’s Weekly” of March 
* A preliminary note announcing the inteedactdons of the grass was 
pabiake in the Report on the Department of Agriculture, Union ot 
South Africa for 1910/1911, p. 241. Here also appears the name Kikuyu 
Grass for the first time. 
+ A short article by Mr. rag vcs in the sponge Journal of 
South Africa, vol. ii., pp. 146-147, di escribes t ined with this 
grass in the Transv aal td them “(1915), and deals with gre uses and 
disadvantages. It also states the circumstances of its introduction, cn 
that with some reserve it ea been referred at Kew to Pennisetw 
longistylum
