1. Kokura State Forest, Minamiazumi County, Nagano Prefecture. 

 The pine groves of this place are situated in a plain where the soil 



is formed of the decomposed granite. The age of the pine trees was 

 about 60 years and they were well grown giving shade enough to protect 

 the soil thus favouring the production of mushrooms. Moreover, Azalea, 

 Enkianthes and other shrubby bushes provide a rich soft humus, and the 

 rootlets of the pine branch out to this raw humus, with its rich layer of 

 " Shiro," which is so favourable to the rich growth of mushrooms. 



2. Crown Forest of Shirasu, Kitatama County, Yamanashi 

 Prefecture. 



Red pine about 100 years old grow on a shallow layer of granite 

 pebbles and the decomposition product, the results of a great inundation 

 in that locality about 100 years ago. Raw humus and bushy grasses are 

 scattered here and there. The pine seedlings that come out either perished 

 or are pulled up by people of the locality in their gathering of grass for 

 forage. The growth of the mushrooms is very irregular and the rootlets 

 of the trees are frequently exposed. 



3. State Forest of Oyama, Atago County, Kyoto Prefecture. 



The underlying rock is granite, having decomposition product of 

 loam with raw humus on it. The pine trees range in age from 30 to 60 

 years and are sufficient close together to retain the moisture of the 

 ground underneath while bushes and coppice also grow well. Where the 

 mushrooms are abundant, the land covering is thin or the ground is 

 very steep. 



4. State Forest of Kamikamo, Atago County, Kyoto Prefecture. 

 The underlying rock which is of Palaeozoic Formation has on it a 



close growth of Akamatsu, 25 years old, while both coppice and bushes 

 grow abundantly. Where Hinoki (Chamaecyparis obtusa S. et Z.) inter- 

 mixed the soil is particularly deep and the mushroom grows well. On 

 other places, where the mushroom grow equally well the soil is mostly 

 shallow or the ground precipitous. 



5. Kinugasa Crown Forest, Kadono County, Kyoto Prefecture. 



The underlying rock of the place, which is of Palaeozoic Formation, 



has but shallow layer of soil with a tree covering of Akamatsu 30 50 



years old and a good covering of bushes and coppice. On ridges, there 

 is but a shallow coating of soil and occasinal cropping out of rocks and
