One orchardist who had used barley sacks successfully for the pur- 
pose of protecting his young orange and prune trees from the attacks 
of the locusts, informed me that some of his neighbors had used papei 
sacks with the result of killing the trees, but I was unable to ascertain 
how much truth there was in this assertion. I saw quite a large num- 
ber of prune and olive trees that were wrav>ped in papers which I was 
informed had been on the trees for three or four weeks, but these trees 
had not been injured in the least by this treatment. A lady owning 
an orchard of young fruit trees near Pasadena found that the leaves 
of several of the trees had been eaten by a kind of May-beetle, Serica 
Jimbriata Lee, which remained hidden from sight in the daytime and 
came forth only at night to feed upon the leaves. Having been applied 
to for advice I recommended that the trees be inclosed in barley sacks, 
and that they be allowed to remain upon the trees for a period of about 
three weeks, or until the May-beetles had passed away. Accordingly 
this was done, and during a recent visit to this orchard I found that the 
sacks had been duly removed and the trees were now growing vigor- 
ously, being to all appearances none the worse for their temporary im- 
prisonment. This would at once disprove the assertion that trees are 
injured by being confined in sacks of this kind. 
Of course, this method could only be employed for the protection of 
small trees ; on large trees it would be altogether too expensive.
