salts of copper, lime and sugar are very unstable, and when sprayed 

 on the fohage probably decompose quickly and liberate copper salts in

Botanic Garden for South Africa. By Mr. N. S. Pillans {Agr. 

 Jour. Cape G. H., June 1910, pp. 638-641).— The estabhshment of a 

 Botanic Garden in the sub-continent is advocated; the author laments 

 the ignorance of the floral resources of the country. The article closes 

 thus: "The garden, once established, would immediately commence 

 to add to the little stock of knowledge now in hand, and by accumu- 

 lating scientific data, investigating and assisting farmers and others in 

 the utilization of economic native plants, and recording practical ex- 

 perience in general horticulture, as well as popularizing and encouraging 

 the cultivation of the most beautiful of the indigenous plants, it would 

 serve every reasonable demand that could be made of any botanic 

 garden." — A. A. K. 



Botanic Gardens, French. By F. Kanngiesser {Oestr. Gart. 

 Zeit. vol. V. pt. X. pp. 384-391). — The Jardin des Plantes at Nancy 

 contains a weeping Fagus silvatica var. tortuosa, grown from a seed of 

 the same variety. A medlar shoot grafted on a Crataegus oxyacantha 

 bears leaves resembling those of the Crataegus ; for four years it bore 

 white flowers, but this year the flowers are pink.

 ference, 4 feet from the ground.
