A new alternaria leaf spot of sapindus emarginatus vahl. from india
Inspite of considerable importance of leaf spot diseases much attention has not so far been paid towards them. Severe infections may be responsible for complete defoliations which may ultimately bring the life of the entire plant at stake. During the last three years the author collected a number of leaf spot flmgi from several new hosts in Maharashtra (India). During the cold season of 1963 the writer noticed a distinct leaf-spot disease oil Sapindus emarginatus VAHL., popularly known as "Soapnut-tree" growing ill the Little Flower School premises, Aurangabad. The disease at tracted special attention due to its severe nature and great economic importance of the tree in India as the soapnuts are used as substitute for soap and in medicine. Critical examination of the fungus in sections as well as in culture showed formation of abundant spores and was later identified as a new species of Alternaria. The disease manifests itself in the form of small, circular spots with ashy black to dark brown spots scattered all over the leaf. These spots could be easily recognised from the spots which were previously reported caused by Phyllosticta.

The Impact of English-only and Bilingual Approaches to EFL Instruction on Low-achieving Bilinguals in Cameroon: An Empirical Study
The aim of this paper is to investigate whether low-achieving bilingual EFL learners perform better in grammar and speaking when French, their first language of literacy, is used in the EFL classroom. A two-phase experiment involving teaching two grammar lessons and two speaking lessons to a control group in English only and to an experimental group with the use of French where appropriate was carried out for the purpose. Each group’s mean percentage improvement after each phase of the experiment was compared to their respective scores in the baseline. The analyses of data revealed that the experimental group obtained the higher mean improvement in the two experiments, both in grammar and speaking tests. This led to the conclusion that the use of French in the EFL classroom does not hinder learning. Rather, French is an effective scaffolding tool in the EFL classroom in Cameroon.
