cerned with the northward extension of the cultivation of fruits 

 and cereals, and comparative cultures at low and high altitudes. 



It is to be recalled in closing that but few plants occupy 

 more than a fraction of all of the possible habitats bv non-con- 

 scious distributional movements, and that the, intelligent consid- 

 eration of the factors of climate and a development cf cultural 

 methods may most readily secure the economic dissemination of 

 plants from the localities in which they do grow to the full range 

 of habitats where they may grow. ISTot only may species be car- 

 ried and established in numberless new localities offering condi- 

 tions equivalent to their natural habitats, but a study of the ad- 

 justments and accommodations of which the plant is capable en- 

 ables or allows it to be introduced into unfamiliar conditions, 

 under which the structural response may take on qualities more 

 valuable than those usually shown by it.

A ROUND TRIP FROM IOWA TO PUGET SOUjSTD.

Among the many interesting places in "the Alps of Amer- 

 ica," Glacier, British Columbia, and Laggan, Alberta, were se- 

 lected for a week's collecting. The former lies in the Selkirk 

 Mountains and the latter in Canadian Rockies. That tourists 

 have gone into ecstacies over Ihese places until the numbers that 

 come often far exceed the present lodging accommodations, is 

 not wondered at by anyone who has once seen the Illecillewaet 

 Valley at Glacier, or Paradise Valley or the Valley of Ten 

 Peaks at Laggan. A botanist of first rank, who has traveled ex- 

 tensively in the Alps says, "there is nothing finer on earth," and 

 the Swiss guides and artists declare that the Alps are not supe- 

 rior for scenery. The Canadian botanists have given a good 

 view of the lichens, mosses and the higher plants, and those in- 

 terested are referred to the Avorks of John Macoun and A. O. 

 Wheeler for data.
