soils. Incidentally it is shown that soil which has never grown vines 

 may be vine-sick. 



The authors extended their experiments with Chrysanthemums, 

 the results being practically invariably in favour of partial steriliza- 

 tion, though the different varieties were, not unanimous in their choice 

 of the sterilizing agent. — A. S.

Stumps, Blowing with Dynamite. By George Roberts (U.S.A. 

 Exp. Stn., Kentucky, Bull. 154; June 1911 ; plates). — There are in 

 various parts of Kentucky areas of considerable extent which are still 

 "in the stumps." This is of course a state of things inconvenient 

 for the use of agricultural machinery and wasteful in space. Stumps 

 are sometimes burned, sometimes pulled, sometimes left to rot, but 

 all these courses have their drawbacks, and the writer shows by the 

 results of actual experiment that the cheapest and quickest method 

 of removing them is by the use of dynamite. — M. L. H. 



Sugar Cane, The Chlorosis of. By P. L. Gile (U.S.A. Exp. Stn., 

 Porto Rico, Ann. Rep. 1911 ; pp. 20, 21). — The bleached cane seems to 

 be confined to patches of very calcareous soil, no cases having occurred 

 in the acid red clays, but green cane has been observed on patches of 

 soil containing as much carbonate of lime as the soil growing chlorotic 

 cane. The leaves of a few high stools in the midst of a strongly affected 

 patch were brushed with a solution of ferrous sulphate and after a few 

 days the leaves became much greener. After several applications of 

 the solution these leaves were killed, but perfectly normal green leaves 

 started out from the top of the canes. Further experiments, both in 

 spraying and in applying iron to the soil, are in progress. — A. P. 



Sweet Peas, American and Telemly. By A. Trebst (Garten- 

 flora, vol. lxi. pt. xvii. pp. 378-381). — The Telemly sweet pea from 

 Algiers begins to flower in March. The dark red varieties are specially 

 valuable, as the American L. odoratus praecox does not yield these 

 colours. Unfortunately the Telemly sorts do not come true from 

 seed, whereas about 90 per cent, of the American do. To ensure a 

 continuation of flowers, podding must be absolutely prevented.
