 similar to the blue-stain fungi belonging to the genus Ceratosto- 

 mella. 



The author notes the natural distribution of the fungus on the 

 resin of spruce and pine in Europe, and discusses its systematic 

 position and connection with other fungi of which it is assumed 

 to be the imperfect stage.

A peculiar method of preserving wood relics 



Wood from decay is outlined by Pinoy. He soaked 



Preservation the wood to saturation in a mixture of 2% 



potassium bichromate and 1% sodium 

 fluoride and exposed to the light and dry air. He then covered 

 with a solution containing 5% gelatine, 2% bichromate and .5% 

 fluoride, which gives the articles a brilliant hard polish and a 

 mahogany color, imitating old wood. The author thinks the 

 method could be quite generally used, and would t)e equally ap- 

 plicable against insects.

Resin Tapping vinces. After tapping 5 years "the tree 

 shall be given a period of rest for ten years." 

 Before tapping commences all trees to be 

 scarred are serially numbered and marked to show the number 

 of pots which can be placed by the contractor. The "heavy tap- 

 ping" (corresponds to "resinize a mort") is only allowed on 

 trees to be felled within 5 years. The following number of 

 pots is allowed: (a) light tapping, i pot on trees 3^' to 4^' girth, 

 2 pots on trees 4^' to 7', 3 pots on trees over /; (b) heavy tap- 

 ping, I pot for each foot of girth. Cups should be equidistant, 

 chipping is "4" wide by i" deep and about 6" long at the base." 

 Chipping after the first incision should not be more than "2^"
