I wish, Mrs. Carr, that I could see your mosses and ferns and lichens. I am sure that you must be happier than anybody else. You have so much less of winter than others; your parlor garden is verdant and in bloom all the year. I took your hint and procured ten or twelve species of moss all in fruit, also a club-moss, a fern, and some liverworts and lichens. I have also a box of thyme. I would go a long way to see your herbarium, more especially your ferns and mosses. These two are by far the most interesting of all the natural orders to me. The shaded hills and glens of Canada are richly ornamented with these lovely plants. _Aspidium spinulosum_ is common everywhere, so also is _A. marginale_., _A. aculeatum_, _A. Lonchitis_, and _A. acrostichoides_ are also abundant in many places. I found specimens of most of the other aspidiums, but those I have mentioned are more common. _Cystopteris bulbifera_ grows in every arbor-vitæ shade in company with the beautiful and fragrant _Linnæa borealis_. _Botrychium lunarioides_ is a common fern in many parts of Canada. _Osmunda regalis_ is far less common here than in Wisconsin. I found it in only two localities. Six _Claytoniana_ only in one place near the Niagara Falls. The delicate _Adiantum_ trembles upon every hillside. _Struthiopteris Germanica_ grows to a great height in open places in arbor-vitæ and black ash swamps. _Camptosorus rhizophyllus_ and _Scolopendrium officinarum_ I found in but one place, amid the wet limestone rocks of Owen Sound. There are many species of sedge common here which I do not remember having seen in Wisconsin. _Calypso borealis_ is a lovely plant found in a few places in dark hemlock woods. But this is an endless thing; I may as well stop here.
