Then as now, it was a time of inflation, high taxes, loyalty oaths—and anxiety. Then as now, arrogance and ignorance did their evil work.Miss Starkey, as always, has so steeped herself in the records left by plain people that the book reads like a novel, although there is not one word of fiction in it.

Horse chestnut ( Aesculus hippocastanum L.) is a common urban tree species in Ljubljana, the capital of Slovenia. This area is forecast to experience a general reduction in precipitation and an increase in temperature, which increases water demand in plants. Because A. hippocastanum is known for its drought vulnerability, the question of the future suitability of this urban tree species in Ljubljana has arisen. To investigate how climate has influenced A. hippocastanum radial growth and how trees responded to extreme climatic events, standardized precipitation-evapotranspiration index (SPEI) was used as a proxy for water demand. Climatic signal and its stability through time were calculated using Pearson’s correlation coefficient. Additionally, to investigate whether the trees had a common response to extreme climatic events, pointer years were calculated using Cropper values. We sampled 19 trees that were growing in Tivoli Park in Ljubljana. After successful cross-dating of 15 trees, the ring count showed that the trees had up to 201 tree-rings and had 130 on average. Climate-tree growth analysis showed that in July, 3-month SPEI had the strongest influence on radial growth, but its influence on radial growth decreased over time, possibly due to the die-off process of trees. The narrowest tree-rings were a result of unusually dry periods at the time of cambium activity and/or new cell growth. With the forecast of longer, more frequent summer drought periods in Ljubljana, soil moisture stress will increase, and as a result, a decrease in radial tree growth of A. hippocastanum trees from Tivoli Park is expected.

V začetku februarja 1999 je sneg poškodoval veliko dreves v Mestni občini Ljubljana. Od 624 dreves, zajetih v naši raziskavi, je bilo kar 195 (31 %) poškodovanih zaradi snega. V povprečju smo zabeležili 1,7 odloma na drevo. Poškodovanih je bilo 17 drevesnih vrst. Najpogosteje zastopane so bile Aesculus hippocastanum L., Betula pendula ROTH. in Salix x sepulcralis SIMONK.Razkroj lesa je bil najpogostejša napaka na mestu odloma. Praviloma se je pojavljal v kombinaciji z vraslo skorjo in bližnjo mehansko poškodbo. Na mestu odloma je bil razkroj zabeležen pri 87 % vej in vrhov premera nad 20 cm.Raziskava je pokazala, da neugodne rastne posebnosti drevesa ter razkrojni procesi v lesu odločilneje vplivajo na lomljenje vej kot sama drevesna vrsta. Odlomljeni deli polovice v snegolomu poškodovanih dreves so ovirali promet alipa povzročili materialno škodo. Z opravljanjem rednega nadzora varnostnega stanja dreves bi bilo mogoče pravočasno odkriti in odstraniti potencialno nevarna drevesa ali njihove dele. Raziskava kaže na nujno uvedbo sistemskega varnostnega nadzora in nege urbanega drevja v Ljubljani. As a result of heavy snow in February 1999, trees were damaged in the City of Ljubljana, Slovenia. Of the investigated 624 trees, 195 (31%) were damaged by snow. On average, 1.7 branch and top per tree were broken. Snow damaged 17 tree species, affecting particularly Aesculus hippocastanum L. and, to a lesser extent, Betula pendula ROTH. and Salix x sepulcralis SIMONK. Decay was the most frequent defect at the failure location and was often associated withincluded bark and vicinity of old mechanical wounds. 87% of broken branches and tops with diameter exceeding 20 cm were decayed at failure location. The research showed that failures were associated rather with structural growth defects and wood decay than with tree species. Broken parts of half of all damaged trees impeded the traffic or caused material damages. Regular control of the trees' safety stage would enable early identification and removal of potentially hazardous trees and their parts. The research demonstrates a necessity for a systematic tree control and proper urban tree care in the City of Ljubljana.

Visoki pajesen je ena bolj razširjenih tujerodnih drevesnih vrst v Sloveniji. Najpogosteje se razrašča zunaj gozda, včasih pa ga najdemo tudi v gozdnem prostoru. V naših gozdovih je kemično zatiranje prepovedano, zato smo preizkusili tri vrste mehanskega zatiranja te vrste. Najuspešnejša metoda je bila puljenje celotnih osebkov, najmanj pa lomljenje enoletnih poganjkov. Mehansko zatiranje je najučinkovitejše, če ga kombiniramo z drugimi ukrepi, kot so: malopovršinsko pomlajevanje, skrb za polnilno plast, uporaba gozdnogojitvenih sistemov, ki pospešujejo vrstno in strukturno pestrost sestojev ter pospeševanje in sajenje hitrorastočih, rastišču primernih domorodnih vrst. The tree of heaven is one of the most widespread non-native tree species in Slovenia. In most areas, its spread occurs in non-forested areas, yet recent observations indicate it is becoming more common within some forest ecosystems as well. Because chemical treatment is banned in Slovenia, this study tested the effectiveness of three mechanical control treatments. Breakage of annual and biennial shoots was not successful the best treatment was total removal by pulling seedlings and saplings. Mechanical control of invasive tree species is more effective if combined with other management approaches, such as practicing silviculture that promotes vertically diverse stands of native tree and shrub species, particularly small-scale silviculture that maintains a subcanopy layer.

Miss Starkey, author of the famed Death in Massachusetts, with her customary magic touch here deals with the tragic interplay of arrogance in high places and ignorance in low. TIME: the wake of the American Revolution PLACE: western Massachusetts SUBJECT: the series of revolts culminating in Shays’ Rebellion PROVOCATION: plain human misery and the heartbreak and disillusionment that await the victors of wars The Yankee farmer, having thrown off the tyranny of the British King, dreamed of a Utopia in which taxes would be trifling and debts remitted. Instead they faced the harsh edicts of the Boston aristocrats. Was this not enough to anger a man? So the embattled farmers of ‘76 once more picked up their muskets and took to the road, animated by the same spirit that had moved them 10 years before. They were supported by much of the old revolutionary paraphernalia: county conventions, committees of correspondence, resources solemnly taken. It wasn’t a long war. But it had consequences. No event that called Washington back to public life and impelled thirteen state governments of violently divergent interests to form a more perfect union can be lightly dismissed. Both sides soon invented their devils, for we have always been eager to believe, especially in rural America, in some great but essentially simple conspiracy in high places.
