HENRY FRANCIS WALLING. 
the east, took up liis old business of map-making at Boston. 
Here he was again engaged for several years under the au¬ 
spices of the State of Massachusetts in correcting and adding 
new data to the State map of Massachusetts, originally pub¬ 
lished in 1842. The result was an imperial quarto atlas of 
the State published in 1871 by H. F. Walling and A. 0. 
Gray, which was very creditable to them and a decided step 
forward. But it did not satisfy Mr. Walling; none knew better 
than he its many imperfections. Resting as it did upon a 
practically perfect basis in the triangulation, executed be¬ 
tween 1834 and 1841, under the direction of Mr. Simeon 
Borden, upon which the State of Massachusetts had ex¬ 
pended over $70,000, Mr. Walling knew that the topo¬ 
graphical details were by no means of the same order of 
precision. 
Mr. Walling had been brought much into contact with 
Mr. Borden between 1850 and 1856, while he was engaged 
in making and publishing the town maps of Massachusetts. 
He was in the habit of consulting him and coming to him 
for information, as he did to the writer of this notice, espe¬ 
cially after Mr. Borden’s death, in 1856. [It was in these 
years, from 1-856 to 1862, that I saw most of him and learned 
to value rightly his many excellent qualities. The events 
of the war and subsequent duty south of New England for 
many years deprived me of opportunities of personal inter¬ 
course with him until my removal to Washington in 1884.] 
He had made many surveys and maps in the meantime. 
Among his plans was one for a general map of the United 
States. To this end he had made a very elaborate collection 
of all obtainable atlas maps of every part of our country. 
This very useful and valuable collection is now the property 
of the Coast and Geodetic Survey, purchased from Mr. Wall¬ 
ing in 1884. 
At that time he had been several years in the service of 
the Coast and Geodetic Survey, where he had rendered faith¬ 
ful service, as he did everywhere.
