difficulties in the way of carrying out the former scheme and abandoned 
it. In July, 1859, he writes to a friend as follows: 
Since I left the office I have had several offers from various States to continue my 
work; and probably in the autumn I may make some arrangement with them, but 
at present am collecting material for a large work on entomology, more especially 
connected with agriculture. Ihave already in four months etched and nearly finished 
twelve copper plates, large octavo, comprising nearly 150 of our principal Coleoptera, 
beginning with the Cicindelidw and Carabida, as beneficial to the agriculturist, inas- 
much as both larva and imago destroy other insects injurious to the crops. I intend 
at the same time, to make my work useful to the entomological student, as I shall 
figure specimens of all the leading families unconnected with agriculture; and as 
there is no such work in America, Iam encouraged by the scientific men here. The 
work will not be finished for at least three years, but by that time I hope to have at 
least 1,500 to 1,800 specimens etched and colored.* 
Of the habits of his life at this time, not dissimilar to the habits of 
his later years, the same letter gives a number of hints. He calls it a 
‘hermit’s life: up at 6 or 7, breakast in his “den” (the writer of this can 
readily picture both “ breakfast” and “‘ den”), after which he smoked 
‘‘a hookah” (nearly ten years later he gave up smoking altogether) ; 
the rest of the day, until 5 o’clock, being given up to the arrangement 
of his specimens and to etching. 
Then he took a restaurant dinner, “ Jewish passover fashion, with 
cap or hat on,” after which he hunted for specimens, and returned home 
about 8 o’clock in the evening. From that time until 10 o’clock he made 
his notes of the day, searched for references, and then to bed. An ex- 
acting task-master, he applied himself without cessation, inaugurating 
that severe routine in his labors, with little or no recreation, which 
marked the last ten years of his life. At this time he wrote: “My 
maxim now is ‘nulla dies sine linea,’ and it is astonishing at the end of 
three months to see what the motto will accomplish.” But the results 
are due not to the motto, but to the persistent application, which in Mr. 
Glover was second nature—more marked in his case than in that of 
many men who perhaps have produced greater results, for he liter- 
ally did not allow himself any recreation besides that which was de- 
manded for the hours of sleeping and refreshment. 
To his cousin, Abram Clapham, of Leeds, England, he writes at this 
time as follows: 
If yoa can procure me specimens of your common British insects, without trouble, I 
would bé much obliged, as I want them for comparison, to find corresponding types 
here, aud to see what differences there are between our Agrotide and the cut- 
worms of England, as I believe that many will be found to be perfectly identical 
Several insects have been imported we all know. Take, for example, the Gale- 
ruca calmariensis, which is even at the present moment destroying all our European 
* His work was commenced about March 1, 1859, From that time to the date of 
his entering the Department of Agriculture, in 1863, was about four years. He held 
the position of United States entomologist just fifteen years to a day, making nine- 
teen years of labor upon his undertaking up to the time it was so suddenly discon- 
tinued by the breaking down of his health. How many more years he would have 
worked upon it, had health been spared, it is difficult to say.
