~ three the expedition was arranged, and the explorer set out by 
Sailing vessel for Paraguay in the summer of 1888. 
A botanical collector was never better equipped. Even the 
wooden cases in which the collections were sent home were taken 
along in pieces with a supply of screws for fastening them toge- 
ther. After a necessarily uneventful voyage of 67 days, the 
vessel reached Buenos Ayres, and a few days were spent there in 
Consultation with some of the local naturalists, and a few plants 
collected. But Paraguay was the region chosen, and within a few 
weeks the explorer was settled in Assumption, and immediately 
began the work of collecting and of carefully recording in note 
books all the gross features of the plants obtained. These note 
books were most systematically kept, and they enabled him on his 
"sturn to write up the account of his collections in a manner which 
has rarely been equalled. With Assumption as a centre, Central 
Paraguay was carefully explored for nearly a year. Opportunity 
was then offered for an examination of the flora of the boundary 
region between Paraguay and the Argentine Republic along the 
Pilcomayo River, through the operations of a surveying party, 
Which ascended that stream ina small steamer. Our friend gladly 
accepted the Opportunity of accompanying the party in the capa- 
city of naturalist, and the stream was ascended several hundred 
miles, the journey only being cut short by the lack of water in the 
"PPet reaches. After several months’ absence, a safe return was 
“flected to Assumption, all the botanical collections being brought 
down unharmed. After a few weeks more spent in and about 
Assumption, Mr. Morong proceeded to Buenos Ayres, and took : 
Passage on the steamer for Valparaiso, Chile. A stop was made : 
* the Falkland Islands, and a few additions there made to the 
already very rich collections. te 
Joining his brother at Coquimbo, advantage was taken of the 
°PPortunity of studying the Atacama desert flora, and considerable 
‘ollections made there and at other points in Chile. In the fall of 
1890 he returned to the United States by steamer to the Isthmus, 
and thence to New Orleans and by rail to New York, having been 
absent considerably more than two years, during which time he 
_ €njoyed continuous good health and encountered a tata | 
“ariety of pleasant experiences. He has frequently alluded to this se
