i he ec|ui|)nirnt of hydraulic Jiiachinery also includes 

 turbines of the (iirard and I'rancis types, and a hi(<h- 

 pressiMC piiMip for operating an experimental I'nginc of 

 the Mrotherhood lype. 



Ihe heal-engine equipment consists of a representative 

 set of machines arranged along one side of the laboratory, 

 and spanned by an overhead crane capable of delivering 

 a load of ,)o cwl. lo .1 lathe at one end. The engines 

 already installed comprise a 12 horse-power " National " 

 gas engine, with special thermometer pockets in the 

 cylinder walls, and arr.ingements for releasing and shutting 

 down the valves at any moment. 'J'his engine ran bi- run 

 on town gas or on suction gas from a producer. A 

 (1 horse-power oil engine has similar lh<rnu)n'.et<'r pockets

ton " Bucktoo " testing machine, a combined bending and 

 twisting machine, and a number of other machines for 

 sm.ill-sc.ile experiments. A specially designed machine for 

 conipri'ssion up lo lifly tons will also be installed. 



The drawing otiice, over the engineering laboratory, is 

 a well-lighted room So feet long and 34 feet wide, with 

 accommodation for one hundred students. 



The college workshops have been recently equipped wilh 

 the most modern tools, and in addition a special shop for 

 the construction and rep.iir of apparatus is provided in 

 Ihe engineering labor.ilory. The n<w wing also contains 

 a lecture theatre and rooms for the staff. 



.As will be apparent from this brief description, the 

 equipment has been designed with the purpose of giving 

 students a practical acquaintance with as wide a field of 

 engineering as possible. All the machinery .ind apparatus 

 ar.' of n'.oderale din.ensions, easily handled by students

.An experinunla! " l.inde " refrigerating plant is 

 arranged lo \.'ork wilh carbonic acid or ammonia by using 

 interchangeable cylinders. The compressing pump is 

 <lrive[i by a motor operating through a worm-wheel gear, 

 so arranged that by disconnecting the pump coupling ex- 

 periments can be made on the efficiency of worm gearing. 



.A small vertical steam engine, a petrol motor, a 



Rider" hot-air engine, and a pulsometer pump are also 

 included, while spaces are reserved for an experimental 

 reciprocating steam engine of compound or triple ex- 

 pansion type, and an independent condensing plant to be 

 installed at an early date. The steam-raising plant will 

 consist of a Yarrow water-lube boiler, ;uul a separately 

 fired superheater.

 running expenses. 



While instruction, not research, h.is beiii the primary 

 object, there is lillle doubt that in ihe future original 

 work can be accomplished which will be of interest and 

 value lo the engineering profession. R. G. CoKER.
