Under the above heading, the Monthly, in the number for December, at page 371, refers to a Bulletin (No. 7) of the Agricultural College of Michigan, which alleges that Catalpas, bignoni-oides and speciosa, and also Teas' hybrid, are tender in Michigan; and that the two former are about equally hardy. I will not undertake to question the statement, so far as their hardiness at so unfavorable a locality as the College Farm is concerned, farther than to say, that this is the only locality in southern Michigan, from which we have heard a complaint that C. speciosa is not entirely hardy.

Forty years ago we planted and grew C. big-nonioides for many years in eastern Michigan; and very rarely succeded in carrying it through the winter unharmed; and others in that region on various soils, experienced the same difficulty. There are now standing in the streets of this village, within half a mile of Lake Michigan, in a vicinity where the peach is a staple orchard fruit, several trees of C. bignonioides, in a sadly diseased condition, obviously from the effect of our winters. On the other hand, we have, for the same forty years, known a tree of C. speciosa, which, the last time we saw it, (three years since,) was in perfect health. We have also, for seven years past, grown both speciosa and Teas' Hybrid, and planted them here, in western Michigan, as roadside and yard trees, as well as in nursery; and we have very rarely, if ever, observed any injury whatever to either, attributable to the cold of our winters. In fact a hundred or two of speciosa and Teas' Hybrid, of two-year seedlings, stood through the unusually severe and continuous cold of last winter, in nursery rows, in a very bleak exposure, uninjured; and have made a vigorous, healthy growth this past summer. Roadside trees of speciosa, three to five years planted, have done equally well, showing no injury whatever.
