N. SALAMAN. Male sterility in Potatoes, a dominant Men- 

 delian Character, with remarks on the shape of the 

 pollen in wild and domestic varieties. (Linncean Society, 

 June 16, 1910). Nature, vol. 84, London, July 7, 1910, p. 29. 



Experiments at Barley near Royston, Herts, during the past 

 four years. 



The author points out that " dead " pollen grains, or none, are 

 usually associated with flowers of heliotrope colour. 



Effect of a Change of Locality on the Vigour of the Po- 

 tato plant. (Report on Experiments with potatoes in 1909, by 

 Mr. Stewart, of the Edinburgh and East of Scotland Agricultural 

 College). -- Note in Nature, Vol. 84. July 14, 1910. p. 50. 



The best change of locality is from a later or colder district 

 to one earlier or warmer. Thus in the South East of Scotland it 

 was found advantageous to procure seed from the north, just as in 

 England it is found profitable to procure seed from Scotland or 

 Ireland. 



Planting Potatoes. (Lanes. C. C. Agric. Dpt. Bull. n. io}. The 

 Journal Board of Agric. London. August 1909, p. 403). 



This Bulletin gives the results ot the experiments with seed 

 potatoes which have been carried on for the four years 1905-8. 

 The two points investigated were the effect of change of seed, and 

 the benefits of boxing and sprouting. 



The conclusion arrived at are as follows: 



1) Seed potatoes brought from a northern to a southern la- 

 titude give a much larger crop than do those brought from a southern 

 to a northern latitude. 



2) The yield from Irish-grown seed sprouted, though highly 

 satisfactory, is, on the average, below that from the Scottish-grown 

 seed sprouted. It is evident, however, that Ireland may become, 

 in the near future, a strong competitor with Scotland as a source 

 of seed potatoes for Lancashire, especially if the respective costs 



transit are taken into consideration. 

 3) Seed potatoes obtained from localities within the county 

 1 on the average to produce crops as large as those obtained 

 from Scottish or Irish-grown seed.
