April 17, 1 910. We left on the morning train for a day in the 

 Helderbergs. We crossed the fields from Meadowvale to the 

 west amphitheater and ascended the rugged rocky ravine to the 

 mouth of Hailes' Cavern. No snow in Helmus Crack or at the 

 base of the waterfalls, although a little in the ravine in spots, 

 about which spring flowers were blooming. There were some 

 banks of snow in the open fields at the top of the cliffs. 



There is a beautiful view over the forested enclosed valley of 

 the west amphitheater from the cliffs. Canoe birch trees are 

 very conspicuous to-day. Last season's fronds of evergreen 

 ferns closely pressed to the ground ; indeed the hea\^' weight of 

 the snow has pressed flat the grass and weeds. The body of a 

 muskrat, at the base of the cliff, near Little Fall. A good day 

 for lichens and mosses, because of the mist\' rain. Descended 

 the short-cut trail to the railroad station, and late in the after- 

 noon went down the railroad track towards Altamont, about a 

 mile, to a piece of woods.
