interest to state that we were forced to shoot with a rifle the 

 blossoms we wanted from the ti^s of the hi^h branches. 



The Pawpaw, Asimina triloba, also required some searching 

 for but at last was found on the main land nearby. The trees 

 fotmd were, comparatively speaking, small saplings, but we heard 

 of one, not far away, with a trunk eight inches in diameter. 



Sycamore, Plaionus occidentalus , also grows to great size 

 on the Point, but the gnarled state of the branches show that it 

 has reached the northern limit of its range. An occurence just 

 before we arrived showed the cause of the dense clumps of 

 twisted twigs, withches brooms, and the strange irregular twists 

 and angles of growth, that adorn the branches of most of these 

 trees on the Point. A frost came after the first leaves had opened, 

 blighting thern .and the delicate twigs thev were giving rise to. 

 For some time thereafter all appearance of terminal growth 

 stOj)ped but later shoots were thrown out at the sides, which 

 being in newdirections, formed fresh angles in the crooked growth 

 of the limbs and bunches of bushy sprouts about the joints. 

 This injures the appearance of the trees but evidently has but 

 little effect on its general health. From the appearance of most 

 of the trees it would seem that these late frosts blight the svca- 

 more,, on Point Pelee, in this manner most years. 



One of the most common trees is the Hackberrv, Celtis 

 occidentalis, which groAvs to great size. Its bark is deeph^ 

 and closely longitudinally ribbed. Thfe ribs sometimes being an 

 inch high, and a quarter of an inch apart. It has a small fruit, 

 black when ripe, mtich liked by birds^ especially the Evening 

 Grosbeak and the Waxings. 



The Poison Ivy, Rhus Toxicodendron, var. radicans, is also 

 interesting to the visitor from other parts of Canada who knows 

 the plant only as a low growing or trailing vine. Here it assumes 

 great size and we brought home a trunk four inches in diameter 

 and fourteen feet long. In one case we saw where an ivy vine had 

 grown to even larger proportions about a tree which subsequently 

 died and rotted away, leaving the clinging vine standing like a 

 tree with great forked branches reaching out in true limb-like 

 pose. 



The Wild Grape, Viiis bicolor, grows to great size. One old 

 and decayed vine measured eight inches in diameter at base, 

 and must have run up thirty feet from the ground without 

 branch or foliage.
