The extra labor in trans])lnntinfi: is fully offset by tbe saving in labor of 

 \v< ediiig and tliiiuiiug', and as tbe yield is greater from tbe transplanted 

 croi) it follows tbat transplanted onions can be grown cheaper per 

 bushel than those grown in the ordinary way.

 acconnt of the downy mildew fungus [Peyonospora viticola) and its effects 

 on the grape, with statements regarding exi)eriments by fruit growers 

 in Ohio in 1890 with eau celeste, ammoniacal solution of carbonate of 

 copper, and copperas. Eau celeste uniformly gave good results, car. 

 bonate of copper was variable in. its action, and copperas proved inef-

Black knot on plums, G. C. Butz, M. S. (pp. 3, 4, illustrated). — 

 The black knot {rioicrighda morhosa) of the plum is brietly described 

 and growers are urged to destroy it on both tbe wild and cultivated 

 plums and cherries. The disease may i)ro[)agate itself in winter as well 

 as in summer. 



"The simplest and most effectual remedy for this disease is to cut 

 away the branches on which the warts ap[)ear, which may require the 

 sacrifice of a large portion of the tree should the excrescence be found 

 on heavy limbs. November and December are good months in which 

 to tlo this work. Mvery piece of icoocl in ichich the fimgiis occurs should 

 he collected and hnrned at once, as the winter spores are known to have 

 ripened in severed branches. Burning the material is, therefoi'e, an 

 essential part of the remedy. Every trace of the disease should be 

 destroyed, not only from one orchard but from neighboring orchards." 



To test the efficiency of slicing off the excrescenses on old branches 

 the author cut off' knots which " ai)peared low down on healthy branches," 

 and only two of them returned.
