tensive experiments on apples, in order to get our bearings and we are 

 not getting results as qnickly and easily on our apples as on our peaches. 

 I think the principles are the same except the peach is the grossest feeder 

 and responds to the fertilizers a little better. I think that the Japanese 

 ])lum would behave much the same and for the same reason. 



X member: Forty years ago I had a Iteautiful four-year-old orchard 

 which all went out in yellows in less than two years. Scattered here and 

 there in that orchard were yellow peaches double the size that they 

 should be at the time. I can remember very distinctly of hearing that 

 the "j^ellows" were disseminated through the blossoms and I would like 

 to know how it could be. 



Prof. Waite: We suspect this to bo the way it is disseminated, but 

 we do not know. 



Mr. Welch : Do you have any idea that there is anything in the 

 ground that might have a tendency to produce the yellows disease. 



Mr. Waite: I think not. 



Mr. Pugley : How will we know whether a tree needs lime? 



Answer: The only way I have of finding that out is to give it some 

 and see how- it responds. In Maryland, we assume that the land needs 

 lime, because the water is soft while here the water is hard and so there 

 is not so much need of it here. The best way to try it out is to put in a 

 duplicate strip lime one and not the other. We see it in the cow pea 

 and cover crops and we can also tell it on the ground by the behaviour 

 of the weeds, the horse sorrel, etc. You can also tell it on the peach 

 tree. When the peach tree is green the tree is deficient in lime. There 

 are three or four different things that show this, one of them being the 

 rolling of the leaves. 



Question: Will the lime correct the acidity of the soil? 



Prof. Waite: Yes, sir. I have a suspicion that much of our land 

 needs lime. • 



A member: I would like to ask if there is any difference in lime? 

 We have been told during the last year that there is no difference. What 

 will be a fair application to a peach orchard? 



Prof. Waite: The lime in different sections of the United States varies 

 considerably. Dr. Lay found out that while plants needed a certain 

 amount of magnesia in the soil, tlie}- did not want too large a proportion 

 of magnesia in lime and so a lime with too much magnesia would not 

 be desirable; and yet, there are peculiar situations in which they might 

 be a remedy for the soil conditions. 



As far as the agricultural lime and stone lime is concerned a good 

 deal that is said about that is fake. If you want to get lime you send to 

 the lime company and you get it in lots of lump lime and this can be 

 a])])lied in two or three different ways. One simple way is to haul it to 

 ilie field, fill a basket and drop it in piles the proper distance apart. 

 Some plough furrows the desired distance apart and put it in these fur- 

 rows. About one ton or 25 bushels to the acre is a good satisfactory 

 application and it will last for four or five years. No one likes to apply 

 too much lime to his land because it burns out the land and causes the 

 soil germs to grow too rapidly and consume too much of the nitrogen 

 and is therefor not desirable. . Any good user of lime will follow it 

 with green manure and cover crops, promptly. Apply lime to the same
