about them. The subcortical mycelium may give rise to the purplish- 

 black rhizomorphic strands, which grow out into the soil to a considerable 

 distance, in one case about ten fest. It was early found in these 

 investigations that the disease is confined to those orchards that were 

 planted on recently cleared timber land. It is added that the application 

 of any fungicida, as a remsdial agent, cannot ba recommsnded at all.

Salt-marsh Lands, Reclamation of. By Thos. H. Means (U.S.A. 

 Dep. Agr., Bur. Soils, Circ. No. 8 ; 1901). — An inquiry was made into 

 the feasibility of reclaiming the salt-marsh lands of the States w^hich 

 border the Atlantic or Pacific Ocean. Attention is drawn to the fact 

 that the reclaimed salt-marshes of Europe are considered the most fertile 

 of soils, and that in England probably more than 1,030,039 acres of fen 

 lands have been succ3ssfully drained and are now in a most fertile 

 condition. 



Notes on the reclamation process, washing out the salt, and cultivation 

 of marsh, together with the most suitable crops for assisting in the work, 

 are given. 



The agricultural value of the salt marshes, with tables of both chemical 

 and mechanical analysis, is set forth. And it is quoted that " one acre 

 of reclaimed marsh land is worth four or five acres of upland, and the 

 cost of reclamation should not exceed one-fifth of the final value of the 

 land."— F. H.
