^^'c sprayed the tree^^ in the park? in the eity of Hoboken princi- 

 pally for the tussock moth caterpillar. The remedy that we used 

 \vas arsenate of lead, and the results were more than satisfactory'. 

 AVe used a i'iold force pump Avith a one-hundred-and-fifty-gallon 

 tank, and about eight pounds of the arsenate to the one hundred 

 and fifty gallons, though we believe that a less amount would be 

 quite efficacious. We do not "believe there is another city in the 

 United States, and we say this without reserve, A\^iere the trees are 

 in such a deplorable condition as in the city of Hoboken. It is 

 qnite an easy matte^r to pull off large cakes of the tussock moth 

 cocoons and eggs a foot square. We only gave the trees one appli- 

 cation at just about the time the caterpillars were commencing to 

 feed, and we strongly urged the council to give us an opportunity 

 to give the trees a second application when the second batch of 

 caterpillars appeared, but unfortunately they allowed this to go by 

 default. 



For San Jose scale we have used "Scalecide" to splendid ad- 

 vantage ; in fact, it is the best thing we have discovered up to date. 

 We have also used ^'Horicrmi" with equally good results. 



In treating the trees of the town of Tiutherford we sprayed prin- 

 cipally for sucking insects, and used an application of whale oil 

 soi\p, Avith a small proportion of tobacco juice added. We were 

 quite pleased Avith the results of this application. 



AVe find that there is now being quite an interest manifested in 

 the preservation of the trees in most tOAvns, and Ave believe this is 

 brought about throngh the efforts of the Experimental Station and 

 tlie shade tree commissions. 



AVe haA'e Avorked on the basis of $25 per day for our outfit, but 

 there is little profit iti it at that rate, and we propose to increase 

 our charo'os to from $30 to $35, according to the caliber of the trees 

 Avhich we nuiy have to treat. We belicA-e that orchard spraying can 

 be done for as Ioav as $10 to $12 per day, and Avhere a farmer oavus 

 the machine f(n' a good deal less.
