I'm about halfway through this, and I'm finding problems with it that have little to do with the 'botanizing' which is the official purpose of the book. If the purpose of the book is to supply botanical information (much of which I could have provided myself with very little difficulty, having lived in more or less the same sort of environment further west), more drawings would be almost obligatory. Giving the Latin names for plants does NOT identify them to people who've seen them, but who have known only the popular names. Also, black & white photos are virtually useless to convey the rich tints of the environments.
It could be argued that black & white photos were all that were available at the time. This argument is invalid. Not only were there accurately colored drawings, but many people took monochrome photos and added color. This applies not only to sepia tinting. The photos were PAINTED the proper colors--an art which is not sufficiently remembered and celebrated.
Whether Muir himself had the skills to do this sort of thing is not clear. He evidently didn't bring a camera along on this trip, and his notebooks, as published, do not include drawings. The text implies that Muir took samples (leaves, cuttings, etc), but sketches don't seem to have been part of the plan. The few photos do not very well convey what things actually looked like at the time--and more recent photos don't do the area justice, really, either.
The casual racism which is so jarring to current readers is, in fact, quite liberal for the times. This was shortly after the American Civil War. The local people he lodges with are suspicious of outsiders, regarding them as what would later have been called 'carpetbaggers'. They quite reasonably suspect that many of the people who come to provide services to the freedmen are out for personal enrichment, at the expense of both landholders and the very freedmen they were supposedly there to aid. Many were, of course. Others who honestly came to provide assistance were corrupted. This happens with all reform movements. If there had been proper oversight and management of the reformers, it might have become a less corrupting process. The problem was that there was no Marshall to oversee the reforms and Reconstruction itself, and that there was quite a bit of local and outside resistance to land and social reforms.
Muir, however, was not a party to the process at all. He was just there to botanize. If he had come up with a more detailed plan beforehand, he would probably have included a plan to interview the 'herb doctors' he was often mistaken for. They had a lot of lore and records, verbal and written, and could have helped him with things like sketches, distinguishing species, etc.
It's evident that Muir had no idea how malaria was transmitted. He speaks of a vapor theory of transmission (reflected in the name of the disease, which is Italian for 'bad air'). The Pontine Marshes probably DID smell bad--but the main impact they had on the spread of malaria was that they formed breeding grounds for mosquitoes which spread the disease. If this had been recognized, then protective measures which included preservation of mosquito predators might have been implemented, rather than what too often did happen, which was elimination of the essential wetlands. And Muir himself might have brought along mosquito netting, for those nights when he had to sleep outside.
The part I've found most irritating so far is not the racism--Muir doesn't have much more use for Southern whites than for the freed slaves--it's more a classist contempt he practices. His mockery of the diet of poor people in general seems based on the idea that they had alternatives (what alternatives? He doesn't say), but chose to eat cornbread and bacon instead. The irritating part is rather the attempt to reconcile people to death. I won't have any part of it. It's all spinach. Death IS a bad thing, and I consider attempts to reconcile people to it invidious.
Otherwise, the story so far is a fairly interesting one. I don't think much of maligning reptiles, or of describing ANY plants as 'weeds'--but this sort of thing is actually rarer in Muir than in other works from the period.
A few notes as I read on: (1) Muir accepts uncritically the argument that alligators attack humans unprovoked, with the intention of eating them. This is slander transcribed into libel. It is simply not true that 'we' feel an 'instinctive' repulsion to reptiles. I personally have never felt any such thing. Furthermore, alligators are NOT aggressive, and except for the very oldest, are not large enough to consider any but infant humans prospective prey. The one documented case so far is of a man who attacked an alligator (NOT vice versa) in an attempt to save a dog, which the alligator was indubitably trying to drown as prey. If the human was injured trying to deprive the alligator of its prey, this is NOT an indication that the alligator was prone to attacking humans. Most creatures will fight to keep from being robbed of their prey.
(2) On a related topic, Muir argues that there is 'tropical' vegetation in the Continental US. There may be--in Southern Florida, and along the Gulf Coast. Essentially, the indicator probably best suited to indicate where 'tropical' flora and fauna begin is to check a map showing where alligators leave off and crocodiles begin. This would be extreme southern Florida (the very southernmost tip of the peninsula) and the Florida Keys. Everywhere else, the climate and the lifeforms are SUBtropical.
I tend to take the assertion that glades and forest patches are impassible with a grain of salt. I've lived in and passed through forests quite often, and I've seldom found areas with as much underbrush as is mentioned. And even where there is much in the way of brambles, the only way people get torn as much as Muir described is if they try to rush through the briars. Taking the time to carefully untangle and move the thorny branches aside is laborious, but in the end, it probably takes LESS time than trying to hack and push one's way through.
Later in the book, there are some sketches. Other editions may have more sketches. This would be preferable. One would like to think that the original journal was full of sketches.
Likewise, some maps would have come in handy. Muir describes areas which are not familiar to many modern readers (mostly, the roads either don't go to those places, or they're walled about with berms, hills, and forests nowadays). Though the title causes expectations of descriptions of lands from Kentucky to Northern Florida, these are there, but it's not really clear what the route was. Even a sketch map with a dotted line would be useful. There seems to have been a crossing of the Florida peninsula (north of Lake Okeechobee, I gather, and also well north of where Everglades National Park is now). There is also appended (because, I gather, the original journals were quite short) a description of the author's botanical excursions around Havana, Cuba, and of a trip to California--apparently the first of several by the author.
The botanical studies of Havana are almost certainly long outdated. I don't know how much urban Havana spread out after the 1860s, and how much reversion to urban gardens and forestry there has been since the 1950s. The descriptions given by Muir suggest that part of the coast was sandy desert (with extensive cacti) at the time, but that the city was largely built on a Moorish model (with houses surrounded by walled or fenced gardens, and with large courtyards within residences, with gardens). This may have been only in the richer neighborhoods, away from the coast. The implication in the book is that the harbor neighborhoods were quite heavily paved over--but that there were few farms in the immediate neighborhood of the city. This probably changed over time, but it would require quite a bit of further reading to discover how, and whether it was reversed. Part of Muir's problem was that he was pretty seriously ill with malaria (and probably typhoid) at the time, and so he wasn't able to go far afield.
The California sections began to make me even more uneasy. Other reviewers have commented on Muir's casual racism--but this racism is largely directed toward what Muir calls 'negroes', and, for the time, is quite mild. More worrisome is the almost complete erasure of indigenous peoples from the record. The book was written about thirty years after the Trail of Tears (noteworthy among indigenous 'removal' force-marches by the fact that it was thoroughly documented by the VICTIMS in journals, letters, newspapers, etc).
In Florida, Muir would have traveled through the area after the end of the Seminole Wars (the last of which ended before the American Civil War). In California, this book takes place a few years before the massacre of the Yahi (from which the youth Ishi, who died in 1916, was probably one of the longest-surviving escapees, among those who weren't deported to reservations). Yet the implication is that the Round Hills area which is described in the book was completely uninhabited by humans, though it must once have been a major part of the lands inhabited by native Californians. It's as if Muir had simply blocked the existence of Native Americans entirely from his mind.
I didn't like the description of an area of Southern Alta California very much anyway. It tends to confirm my opinion that the area is not fit for human habitation. I do understand that the indigenous peoples had a lifestyle that didn't require quite so much in the way of resources, but still--the area described is very close to high desert. Though it's observed in a period of unusually high rainfall (and snowmelt--it was early spring), it seems barren and awful to me. I'm unusual in how much I hate sunlight--I recognize that. And I also hate treeless mountains. I don't find them anything like intoxicating or beautiful--they just exude death to me. I find them depressing; in that way I find them impressive. But it's not a kind of impression I'd care to cultivate.
I don't know if this book is typical of Muir's work. I gather that other works, which Muir published himself, were more polished and more carefully edited. I don't know whether they would have been significantly improved in the areas which modern readers find disturbing, however. All in all, while I agree with Muir about many matters (especially about the hubris of humans, and particularly that of what is now described as 'Western' philosophies), I find this book more irritating than enlightening. Perhaps if I had more background in botany (lacking pictures, for example, I often can't say whether I've seen the plants Muir describes), I might feel differently. Meantime, I'll be looking around for an edition with more illustrations. If I don't find one, it's doubtful that I'll read this particular book again.
