TRIP TO HILO. 



The writer left Honolulu on May 11, and returned on May 17. 



The trip Tvas made for the purpose of installing a five horse power 

 steam boiler and a four foot square wooden tank to, be used as a sterilizer 

 at the Hilo Nursery. A trial was made after the boiler and tank were 

 erected and everything was found to work well. I examined the nursery

 coming on. The writer also called on a few of the Waiakea homesteaders 

 who desired advice.
