THE TENT CATERPILLAR. 



Throiicli ooiisliiorablr ulisirvatloii lii 

 some parts of the i<tatr and through au 

 inquiry wliloli has licoii sent out from 

 the Rhode Island State Board of Agri- 

 culture to a number of prominent or- 

 chardists of the state and which has 

 lieen very kindly answered by them, 

 we have ascertained that eggs of the 

 apple tree lent caterpillar are appar- 

 ently about as abundant as they have 

 been during the past three years. 

 Specimen egg clusters examined are in 

 flrst-class condition, indicating that so 

 far as egg parasites are concerned, the 

 chances of a full hatch of caterpillars 

 are excellent. Of course the insects 

 may later meet with destruction In 

 w^ays other than from parasites, but so 

 far as any prophesy is possible at this 

 time, we may look for another year of 

 severe depredations from this pest. It 

 is well, therefore, to take precautions 

 to suppress the insect as far as pos- 

 sible at the beginning of its career. 

 FYuit growers especially should be on 

 their guard. A sharp lookout during 

 pruning time will reveal many egg 

 clusters and they can be cut off and 

 burned. Spraying dormant trees with 

 lime and sulphur or a miscibleoil (win- 

 ter strength) is effective in destroying 

 many tent caterpillar eggs as well as 

 the San Jose scale. If applied just as 

 buds begin to open these sprays are 

 also very helpful in controlling plant 

 lice. Both of these sprays are useful 

 in controlling plant diseases, but the 

 lime and sulphur is preferable from a 

 fungicidal standpoint. 



Should this preliminary spraying fail 

 to destroy all the caterpillars in the 

 egg stage an application of arsenate of 

 lead — 3 pounds to 50 gallons of water

—immediately after the leaves are un- 

 folded is practically a specific against 

 the tent caterpillars and is also useful 

 in controlling bud moth, canker worm 

 and other leaf-eating insects. As it 

 costs but little more, lime and sulphur 

 in summer strength (one gallon con- 

 centrated lime and sulphur to 40 gal- 

 lons of water) should be used as car- 

 rier for the arsenate of lead, since this 

 combination is helpful in still further 

 controlling plant diseases. If desired 

 as a final precaution against the de- 

 velopment of any plant lice which may 

 escape the first spraying, a 40 per cent, 

 nicotine sulphate (Black-leaf 40 or other 

 tobacco extract of like strength) may 

 be added at the rate of % of a pint to 

 .50 gallons of the above spray mixture. 

 All ingredients of this mixture except- 

 ing the arsenate of lead are contact 

 insecticides and it is especially impor- 

 tant that the spraying should be thor- 

 ough so that if any insects are present 

 the liquid may be brought in actual 

 contact with them.

nuts, age of trees and hardiness. 

 Owners of nut trees are urgently re- 

 quested to correspond with the college. 

 It is hoped that this information will 

 be sent in to the department without 

 delay so that the trees may be visited 

 by the investigators and fuller notes 

 and observations made. Whoever is 

 growing such trees is invited to write 

 to F. N. Fagan at State College, Penn- 

 sylvania, giving information both as to 

 the trees and to the property upon 

 which they are located. 



ENGLISH WALNUTS IN PENNSYL- 

 VANIA. 



The English walnut is attracting 

 wide interest in Pennsylvania as a 

 commercial orchard tree. Scarcely a 

 week goes by at the Pennsylvania 

 State College without receiving in- 

 quiries concerning this nut. These in- 

 quiries are usually prompted by the 

 fact that already within the state are 

 bearing trees which have proved both 

 their hardiness and their ability to 

 bear abundant crops of nuts equal or 

 superior to the nuts found in our east- 

 ern markets, which are imported from 

 the Old World, California or Oregon, 

 the principal sources of our commer- 

 cial supply. 



Because of the interest manifested, 

 the Department of Horticulture of the 

 college has planned a thorough inves- 

 tigation of the subject. This will begin 

 with a survey of the state to determine 

 the location of all trees. In order to 

 make this survey as complete as pos- 

 sible, the department urgently re- 

 quests the assistance of every one who 

 can give facts concerning such trees, 

 especially as to location, character of
