§ 129. Companion Plants—I.. H. H.’s observations in § 119, _ 
October Number of the Burretin, will not hold good here; for — 
Cephalanthus and Saururus, while often growing together, are — | 
more frequently found in different localities. As they affect similar 
situations, they would naturally grow in company at times; but 
the former is much the more common plant with us. 
" My experience is also diverse from that of Mr. Bower. I do not 
remember to have ever seen Schizeea pusilla and Lycopodium Caro- * 
linianum in company, though I have seen them in se oti locali- 
ties many times. ‘The former is confined to the Pine-Barren region 
of New Jersey, while the latter extends along the Atlantic coast 
to Florida, and is even found at the Cape of Good Hope !—where, © ae 
too, a species of Schizea (S. pectinata, Thunb.) is also found. It_ 
would be curious if these keep company also; but different localities 
are given on the labels with my specimens. ~ x

§ 130. Insects destroyed by vegetables.—The note (§ 116) 
about grasshoppers, in the October BuLtErin, reminds me of the - 
time when I spent years in looking after insects which suffered 
death either by imprisonment or by attacking plants to deposit 
eggs, ete. I found it common forthe timber boring insects (Uro- 
cerata) to become fastened to the trunks of trees by their oviposi- 
tors. One year I found quite a rumber of the Sirex Columba, L., 
the Tremex of our times, thus fastened to Oaks, Elms, Pear trees, 
ete. I also found that our common Pond-lily (Nymphga odorata) 
closed up, every now and then, confining insects of various sorts, © 
and that, when the flower was mature, the straight scape would be- 
come spiral and draw flower and insects under water. The Gum 
Pink Catchfly [Silene antirrhina?] was visited, and the insects im- __
