Agricultural Shows. 



[may, 



middle or latter half of the rotation they are apt to develop 

 .unsatisfactory symptoms. The kind of soil appears to make 

 no difference, the evil being found on dry sand as v/ell as 

 on good loam. The disease seems to start at certain points and 

 to spread outwards. Scots pines alone are affected, all other 

 trees being apparently immune. 



The direct cause of the trouble has been traced to the attack 

 of two root-fungi, Polypoms annosus and Agaricns melleus^ (or 

 Arinillaria mellea, see p. iii), the latter appearing subsequently 

 to the former and completing its work. Although these 

 parasites are not unknown on other trees- they are chiefly 

 met with on pines. 



The subject is discussed by Forstmeister Frombling in the 

 March issue of the Zeit. filr Forst- inid Jagdwesen^ who advances 

 the theory that trees growing on old tillage land, being more 

 " forced " in youth, have comparatively little power of resistance 

 to attack. The fungi, too, find very favourable conditions of 

 growth on old arable land, the residues of farmyard manure 

 ^nd the open texture of the soil favouring their development. 

 Frombling suggests that where it is intended to afforest arable 

 land the following points should be observed : — (i) Avoid using 

 Scots pines ; (2) Avoid using farmyard manure for some years 

 before planting ; (3) Exhaust the soil by growing two or three 

 corn crops in succession. 



The Board have received from British representatives abroad 

 some particulars relating to agricultural shows held in certain 

 European countries. 

 Sh^^^^^'^^^S^^th principal agricultural shows 



Eastern Europe. ^^^^ South Russia are those of Rostov- 

 on-Don and Elizavetgrad. An account of 

 the former was given in a previous number of this Journal 

 (March, 1906, p. 760). At Elizavetgrad there is an annual show 

 in the autumn, but this will not be held in 1906. There is 

 also a small annual show at Kharkoff for breeding cattle. 

 Numerous horse shows are held in various parts of Russia under 

 the auspices of the Imperial Stud Department of St. Petersburg.
