The joLKXAL of Heredity 



CITY PARK IN KRASNAWODSK. 



The hedge in the foreground is Poinciana gilliesi, and the tall shrubs are Ulmus pumila. 

 Both of these shrubs are valuable for arid climates with scorching summers and mild 

 winters; the former has long been esteemed in the United States. Photograph taken

mined and the others will come in the 

 course of a few years. Some of these 

 Calligonums are strictly local ]jlants 

 and may not readily bear acclimatizing 

 — at least Mr. Palletsky found that the 

 species from around Oremburg and 

 Astrakhan do not stand the long, in- 

 tense heat at Chartchui. 



WORK IN NURSERIES. 



After having seen the large planta- 

 tions, where the plants are now s])read- 

 ing rapidly and require practically no 

 care any longer, we paid a visit to the 

 nurseries where seeds arc sown and 

 young plants raised. They had exper-

 of the plants was not what they wished 

 it to be, still it was interesting to see 

 how the sand was held in check by long 

 straw stretched over it, this kept in place 



again by little sticks set across it at the 

 ends. Hedges of Tamarix sp. and of the 

 wild form of Elaea^nns angiistifoliakept

 sown in the autumn and have to be kept 

 moist as long as they haven't ger- 

 minated; when once above the ground, 

 liowever, great care is necessary in keep- 

 ing them almost dry, as otherwise they 

 ])crish. 



Then Mr. Palletsky showed me with 

 much pride an Opuntia cutting, which 

 he had obtained from us through the 

 St. Petersburg Botanical Garden, and 

 which cutting was growing nicely. He 

 was very grateful to have it, and had 

 six more distributed at different points 

 in Central Asia. But then we began to talk 

 about lowness of temperatures here and 

 he said that the minimum had l:)een 14° 

 Reaumur (ZeroF.). Well, then, I said
