Eanges of narrow houses are giving good satisfaction but the growers are build- 

 ing their new ones of wide separate houses. The merits of the separate houses may 

 be given briefly as follows: 



(1) Side ventilation is recognized as a necessity among vegetable growers, and 

 this can be secured amply by having separate houses. 



(2) Different temperatures may be kept in different houses thus enabling the 

 growing of crops requiring several degrees difference in temperature. 



(3) Heating systems can be built so as to shut off entirely one house if the 

 occasion should so demand. 



(4) Disease is not so liable to spread from one house to another. 



OBJECTION TO JOINED HOUSES. 



(1) Where the rauge is large adequate side ventilation cannot be secured. 



(2) Unless glass partitions are erected in joined houses different crops re- 

 quiring high and low temperatures cannot be successfully grown. 



(3) Heating cannot be regulated in case of accident, etc. 



(4) In joined houses disease will spread quickly from one house to another. 

 In regard to the heating of the two styles of houses it is claimed by owners of 



large ranges that there is very little difference in the cost. Of course some claim 



Large houses built separately are usually joined by an alley house from 10 to 30 ft. in 

 length. The space between the houses is often utilized for hot beds, cold frames, 

 and for such crops as corn, squash, staked tomatoes or rhubarb. 



exorbitant saving on their parficular houses but this cannot always be verified. 

 On the whole separate houses can be heated with practically the same cost as houses 

 on the connected style. 



Alley houses are usually built connecting the separate houses for convenience 

 of carrying supplies, etc.. and the heating main is usually carried through fhese 

 minimizing the loss of heat.
