for the manufacture of catsup, which will do the work almost as fast as they can 

 be shovelled into it, and does the work well. I have no doubt this machine can 

 be used also for extracting seed from currants, grapes, etc. ; some of our canhers 

 are already experimenting with it on grapes, and, if they succeed, this will result 

 in an increased demand for the raw product. 



Last season red currants brought from four to six cents per pound for Raby 

 Castle, and from six to nine cents for Cherry and Fay. The former at above 

 prices brought the most money per acre last season, for the blight on the latter 

 reduced the crop. 



I would say to all who can, plant and grow more currants, at least, if 

 prepared to stand by the above directions ; but if not, let them alone, or you 

 will be like the man who bit off more than he could chew.

Poison for the Cureulio —Many experimenters have tried spraying their 

 plum trees with arsenites to destroy the cureulio, with varying success. Some 

 results of a definite character were given by G. C Davis, of Michigan, in the 

 Stockman. The stung fruit was first all picked off, and then some trees were 

 sprayed and the rest left unsprayed. The trees were then tightly covered with 

 cheese cloth, and curiculios introduced under all. In a week it was found that 

 nearly all the unsprayed fruit was stung. Only 37 per cent, of the sprayed fruit 

 was stung. No dead insects were found under the unsprayed sacking ; but 

 under the sprayed 28 per cent, were dead. It was found that the insect lived 

 two or three days after eating the poison, and thus the remedy was not so prompt 

 as desirable, as they might sting many plums in the interim. Spraying is there- 

 fore only a partial remedy. It should be applied three or four times — first, 

 before blossoming ; and then at intervals afterward, but never while the trees 

 are in bloom to poison bees and honey. Under favorable circumstances it may 

 prove valuable, and sometimes a sufficient remedy for this insect. 



Kerosene Emulsion.— At a recent meeting of the Western Iowa Horti- 

 cultural Society, Capt. C. L. Watrous described a plan for applying kerosene 

 emulsion, which he had seen used in Eastern nurseries. It is especially adapted 

 for plant-lice on young trees, and would appear to be a most effective way of 

 reaching these little pests. No pump is necessary, but the operator takes a large 

 sponge in each hand, dips them into the dish of diluted emulsion, then presses 

 them together on the opposite sides of the stem of the plant or trunk of the 

 tree close to the ground. By a quick upward movement the whole plant is 

 drawn between the sponges, wetting every part, and especially the under sides 

 of the leaves, where the lice are most numerous. 



In this way small trees in nursery rows and garden shrubs can probably be 



treated more quickly and effectually than by spraying. If care is taken in 



pressing out the excess of water when taking sponges from pail and avoiding 



drip from too much pressure when applying, waste of material will be less.
