For the two stands investigated, no and 119 5^ears old, with 

 16 % diseased a loss of round $22. and $24. per acre was found, 

 which discounted with 2.5% to the 80 year, when it is supposed 

 the rot damage began, would make round $10 as the amount 

 up to which expenditures for fighting the disease would have 

 been financially justified.

The dread disease of ' ' Schiitte ' ' (damping 

 Remedy off ?) to which pine seedlings are exposed, 



for is especially calamitous in the Revier of 



''Schiitte'' Fm. Schalk. In the nurseries the grow- 



ing of pine seedlings had to be given up, 

 and plantations kneehigh succumbed to the pest. Bordeaux 

 mixture seemedv to be effective. Curiously enough, an annual 

 contingent of 100,000 pine seedlings from Halstenbeck nurseries 

 used for 7 years remained free from the disease. A trial was 

 made with intensive fertilizing in the nurseries, with Thomas 

 slag, Kainit, Chili saltpetre and lupine. The result was perfect 

 in the very year when the sowings in the forest suffered especially 

 severely. Nitrogen fertilizer (lupine) was most effective. This 

 explains the experience with Halstenbecker stock, which is grown 

 on heavily manured soil ; the resistance to the disease continuing 

 in the plants through the period of danger.
