that means it must run still lower in the price of material, to 

 get a steady benefit from the mulch. At the same time, our 

 mulch results do not show that the mulch is extremely 

 efficient in the securing of growth on young trees, because 

 it conserves a most important thing for young tress, which 

 seems to be moisture. They can usually ferret out their 

 own needs in plant food if you will give them moisture and 

 keeg.it there. In the second place, we have shown the great 

 possibilities of using permanent covers plus the mulch 

 around trees in all situations that are in any way subject to 

 erosion or in which tillage is objectionable for any reason. 

 In addition to that we have shown that in mature orchards, 

 after the trees themselves get out and begin shading the 

 soil, the moisture requirements seem to go down in their 

 relative importance, so far as plant food is concerned, and 

 it looks as if results had shown in those situations that you 

 could gradually reduce the quantity of your mulch and 

 adjust the proper fertilizer to it and go ahead. 



DR. GILSON. What depth do you call the best for 

 mulch ? 



DR. STEWART. Any depth that is sufficient to keep 

 the growth of vegetation down. We use six to twelve 

 inches of a mulch, which is depth enough to keep most of 

 the vegetation down. 



PRES. BARNES OF THE CONNECTICUT POMOLOG- 

 ICAL SOCIETY. I would like to say that the first week 

 in February the Connecticut Pomological Society have their 

 annual meeting, and among other things that are scheduled 

 is an address by Doctor Jenkins of New Haven, bearing on 

 experiments with a peach orchard for a term of years. I 

 think possibly many of us in Connecticut and Massachusetts 

 who are possibly members of this Association are peach 

 growers, and I feel quite sure that address will be of inter- 

 est to all of them, and I hope as many as can will be 

 present at that meeting and hear what the Doctor has to say 

 about those experiments. 



THE PRESIDENT. You will have opportunity, I 

 think, to ask Dr. Stewart some questions as individuals. We 

 have some other business to come up, and I am very aorry 

 to have to ask that the discussion now come to a close. Mr.
