have all of the descriptions comparable 

 and. so far as permissible to make the 

 gross characters the basis for separation. 

 The microscopic features are printed in 

 smaller type than the others, to avoid con- 

 fusion and to simplify the use of the Key. 

 It is comparatively easy to make a key 

 for a given lot of wood specimens, but to 

 take into account the range of variation of 

 each wood is an extremely difficult task. 

 Such a key must be the result of growth, of 

 the accumulation of years of investigation 

 and experience, and must always be sub- 

 ject to revision as new data and new ma- 

 terial become available. To this end the 

 author enlists the co-operation of all read- 

 ers of this magazine. 



Vacation Days in Colorado's National 

 Forests. Issued by the Office of the Dis- 

 trict Forester, District 2, this recreation 

 booklet is guaranteed to create a longing 

 in the heart of every reader for "the hills, 

 whence cometh our help." And nowhere in 

 our wide and beautiful country is this 

 desire more fully met than in the "Switzer- 

 land of America." The National Forests in 

 Colorado hold an opportunity, and an invi- 

 tation to those to whom the impulse comes 

 to leave the heat of the city and business 

 cares behind and follow the open road to 

 the "still places." Nowhere else in the 

 United States, and seldom in any land, 

 may one look upon more majestic vistas 

 of snow-capped mountain ranges, forested 

 slopes, granite gorges, tumbling cascades 

 and rolling plains than in these playgrounds 

 of the people in Colorado. The climate is 

 wonderful — a tonic of sunshine and pure 

 air. filling one with vigor. Few places may 

 be found which offer the seeker after rest, 

 recreation and outdoor life so many oppor- 

 tunities for enjoyment. The booklet de- 

 scribes briefly the National Forests within 

 the boundary of Colorado, stressing par- 

 ticularly points of interest and the privileges 

 extended to prospective visitors and con- 

 tains as well practical advice and informa- 

 tion regarding camping outfits, personal 

 equipment necessary, etc. Further informa- 

 tion may be had by addressing District 

 Forester, District 2, New Federal Building, 

 Denver, Colorado. 



"P NTOMOLOGISTS of the United States 

 Department of Agriculture who last fall 

 began an examination of the cranberry bogs 

 of Michigan, Wisconsin, and the Pacific 

 Coast which have received shipments of 

 cranberry vines from New England report 

 that they find no evidence of gypsy-moth 

 infestations from such shipments. It had 

 been feared that the moth had been car- 

 ried on the vines to the western bogs. De- 

 termination of the fact was necessary in 

 order to know what control measures 

 should be undertaken. In that connection 

 the Department is making tests to deter- 

 mine both the resistance of cranberry vines 

 to intensive fumigation and the strength of 

 fumigation necessary to destroy the eggs 

 of the gypsy moth.

The Laurentide Company, which was the 

 pioneer in grinding hardwood for pulp in 

 an experiment last fall, tried a further one 

 this spring when seventy cords of mixed 

 birch, beech and maple was barked in the 

 drum barkers without any difficulty and 

 ground into pulp. Owing to the irregu 

 larity of the four foot sticks barking with 

 knife barkers was soon proved to be un- 

 successful but the drum barkers removed 

 the bark, if anything, a little more easily 

 from the hardwood than from spruce, the 

 only difficulty was the weight of the wood 

 which is harder on the conveyors. Begin- 

 ning in August the Company will begin to 

 use hardwood continuously. 



The meeting of the Woodlands Section of 

 the Canadian Pulp and Paper Association 

 took place on June 25 and 26. The first 

 day was spent at the Berthier Nursery of 

 the Provincial Government as the guests of 

 Mr. Piche, Chief Forester. The Minister 

 of Lands formally opened the air patrol 

 and the seaplane arrived and left from 

 Berthier for its first trip. The nursery 

 was inspected and also the planting on 

 drifting sands at Berthier and a fine stand 

 of white pine which has been thinned and 

 cared for for a number of years. There 

 was also a general discussion of re- 

 forestation and slash disposal. The meet- 

 ing on the next day was held at Grand 

 Mere and Proulx where the nurseries and 

 experimental plantations were inspected and 

 where tractors were, shown at work and 

 a kerosene brush burner and gasoline fire 

 pump demonstrated. An out door woods- 

 man's lunch was served. A representa- 

 tive of the U. S. Forest Service was pres- 

 ent and a large number of representative 

 pulp and paper and lumbermen were pres- 

 ent with a number of Government and. 

 private Canadian foresters. 



Two trees affected with blister rust 

 have been found in a plantation of Scotch 

 pine planted by the Laurentide Company 

 and have been removed and burned. The 

 white pine weevil has also attacked the 

 same plantation and a fungous disease 

 which has destroyed some of the terminal 

 buds. This latter is now over. If Scotch 

 pine is going to suffer in this way it will 

 hardly pay to plant it in this section. 



Mr. H. G. Schanche, for many years 

 with the Forestry Division of the Lauren- 

 tide Company has become forester for the 

 Abitibi Pulp and Paper Company, Ltd., of 

 Iriquois Falls. They expect to start a 

 nursery at once and begin reforestation on 

 their cut-over lands.

TREES FOR OUR 



HEROIC DEAD 



In the St. Maurice Valley two large fires 

 have been extinguished without loss of 

 merchantable timber but with a large area 

 of cut-over land destroyed. In the earlier 

 days when the areas of timber cut over 

 each year by the various operators were 

 small and widely separated the danger 

 from the heaped up debris was not serious. 

 Today, however, when an area of 126 

 square miles is being cut each year and 

 when the operations of some of the com- 

 panies are contiguous, a dry spell of eight 

 or ten days and a high wind make such 

 areas almost impossible to control and a 

 terrible conflagration will be almost in- 

 evitable. The large number of men re- 

 quired to fight such fires makes them very 

 expensive. The time has come when some 

 Province-wide system of burning slash 

 from lumbering must be inaugurated. 

 Even if the cost should run to a dollar a 

 cord, by being borne equally by all no hard- 

 ship would be incurred and the cost would
